GENERAL DESCRIPTION  
The ADL5335 is a digital gain amplifier (DGA) optimized for  
use in wireless transmitters. A differential input and single-  
ended output facilitates a balun free connection between the  
broadband integrated transceivers with differential outputs and  
the RF gain blocks and drivers amplifiers with single-ended inputs.  
size of 0.5 dB. The ADL5335 also features a fast attack function  
where the gain can rapidly increase or decrease by the  
application of a single pulse.  
The use of a thermometer-based digital step attenuator (DSA)  
ensures that gain changes are fundamentally glitch free. The  
ADL5335 is packaged in a 4 mm × 4 mm, 16-lead LFCSP. A  
fully populated evaluation board and system demonstration  
platform (SDP)-based control software are available.  
The gain is programmable via a standard Analog Devices, Inc.,  
serial peripheral interface (SPI) port from a maximum gain of  
12.0 dB down to a minimum gain of −8.0 dB with a gain step

ESD CAUTION  
1 If the common-mode voltage at the inputs (VCOM) is closer than 0.625 V from  
either rail voltage (VRAIL), the equivalent voltage reduces to (|VRAIL − VCOM|) × 4,  
where VRAIL is the rail closest to VCOM

Stresses at or above those listed under Absolute Maximum  
Ratings may cause permanent damage to the product. This is a  
stress rating only; functional operation of the product at these  
or any other conditions above those indicated in the operational  
section of this specification is not implied. Operation beyond  
the maximum operating conditions for extended periods may  
affect product reliability.

Enable. A logic high on this pin (1.8 V logic) enables operation and a logic low on this pin puts the  
device in a low power sleep mode.  
12  
FA  
Fast Attack. A logic high on this pin (1.8 V logic) decreases the programmed gain by an additional 2 dB,  
4 dB, 8 dB, or 16 dB. The fast attack attenuation step is defined by the last two bits of an 8-bit  
programming byte that is written to the device via the SPI. When FA returns to a logic low, the gain  
returns to its normal programmed level. When not using the fast attack function, tie the FA pin to  
ground.

Serial Data Input/Output (SDIO), 1.8 V Logic. The gain and fast attack attenuation levels are programmed  
using eight bits (Register Address 0x100). The 24-bit write consists of an R/W bit, a 15-bit register  
address, and the eight bits of data. The first six bits of data set the gain and the last two bits set the fast  
attack attenuation (−2 dB, −4 dB, −8 dB, or −16 dB).  
Serial Clock (SCLK), 1.8 V Logic. The gain and fast attack attenuation levels are programmed using eight  
bits (Register Address 0x100). The 24-bit write consists of an R/W bit, a 15-bit register address, and the  
eight bits of data. The first six bits of data set the gain and the last two bits set the fast attack  
attenuation (−2 dB, −4 dB, −8 dB, or −16 dB).  
Chip Select Bar (CS), 1.8 V Logic. The gain and fast attack attenuation levels are programmed using  
eight bits (Register Address 0x100). The 24-bit write consists of an R/W bit, a 15-bit register address,  
and the eight bits of data. The first six bits of data set the gain and the last two bits set the fast attack  
attenuation (−2 dB, −4 dB, −8 dB, or −16 dB).

The ADL5335 is an SPI controlled DGA. An integrated, on-chip  
balun converts a 50 Ω differential RF input into a 50 Ω single-  
ended RF output. The RF inputs and the RF output utilize  
internal ac coupling capacitors.  
The DGA core consists of a fixed gain amplifier and digitally  
controlled attenuator. The amplifier has a gain of 12.0 dB. The  
attenuator has a range of 0 dB to −8.0 dB with +0.5 dB steps and  
uses a thermometer coding technique to eliminate transient  
glitches during gain changes.  
DIGITAL INTERFACE OVERVIEW  
The ADL5335 digital section includes an enable pin (ENBL),  
a fast attack pin (FA), and a SPI.  
Serial Peripheral Interface (SPI)  
The SPI uses the three following pins: the serial data  
input/output (SDIO), the serial clock (SCLK), and the chip  
CS  
select bar ( ).  
The SPI data register consists of three bytes: one read/write bit  
(R/W), 15 address bits (A14 to A0), two fast attack (FA)  
attenuation step size bits (D7 and D6), and six gain control bits  
(D5 to D0), as shown in Figure 24.  
The gain code and fast attack attenuation step size bits are  
controlled via Register Address 0x100. See Table 6 and Table 7,  
respectively, for their truth tables.

The fast attack feature allows the gain to be reduced from its  
present setting by a predetermined step size. Four different  
attenuation step sizes are available (see Table 7).

The FA pin controls fast attack mode. A logic high on the FA  
pin results in an attenuation that is selected by Bits[D7:D6] in  
the SPI register (Register Address 0x100).

APPLICATIONS INFORMATION  
CS  
SDIO, and ), fast attack (FA), and enable (ENBL) pins  
operate at an 1.8 V voltage. To enable the ADL5335, pull the  
ENBL pin high (1.8 V). A low on the ENBL pin sets the device  
to power-down mode, reducing the current to approximately  
3.7 mA.  
BASIC CONNECTIONS  
Figure 25 shows the basic connections for operating the  
ADL5335. Apply a 5 V voltage to the supply pins (VPOS1,  
VPOS2, and VPOS3). Decouple each supply pin with at least  
one low inductance, surface-mount ceramic, 0.1 μF capacitor  
placed as close to the device as possible. The balanced differential  
inputs are decoupled using 100 pF capacitors and so is the 50 Ω  
load on the RF output. The serial peripheral interface pins (SCLK,  
For additional information on device operation, see the
