10MHz, Low Noise, Operational Amplifiers
Features
• Low Noise . . . . . . . . . . . . . . . . . . . . . 3.0nV/√Hz at 1kHz
The HA-5101 is a dielectrically isolated operational amplifier
featuring low noise, (3.0nV/√Hz at 1kHz).
• Bandwidth . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10MHz
• Slew Rate. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10V/µs
DC characteristics of the HA-5101 assure accurate
o
• Low Offset Voltage Drift . . . . . . . . . . . . . . . . . . . . 3µV/ C
performance. The 0.5mV offset voltage is externally adjust-
o

able and offset voltage drift is just 3µV/ C. An offset current
• High Gain . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 x 10 V/V
of only 30nA reduces input current errors and an open loop
• High CMRR/PSRR. . . . . . . . . . . . . . . . . . . . . . . . . 100dB
• High Output Drive Capability . . . . . . . . . . . . . . . . . . 30mA
6
voltage gain of 1 x 10 V/V increases loop gain for low
distortion amplification.
The HA-5101 is ideal for audio applications, especially low-
level signal amplifiers such as microphone, tape head and
phono cartridge preamplifiers. Additionally, it is well suited
for low distortion oscillators, low noise function generators
and high Q filters.
Applications
• High Quality Audio Preamplifiers
• High Q Active Filters
• Low Noise Function Generators
• Low Distortion Oscillators

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
o
1. Maximum power dissipation, including output load, must be designed to maintain the maximum junction temperature below 150 C for the plastic
packages.
2. θJA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379
for details.

Input Protection
The HA-5101 has built-in back-to-back protection diodes
which will limit the differential input voltage to approximately

HA-5101
7V. If the 5101 will be used in conditions where that voltage
may be exceeded, then current limiting resistors must be
used. No more than 25mA should be allowed to flow in the
HA-5101’s input.
If saturation cannot be avoided the HA-5101 recovers from a
25% overdrive in about 6.5µs (see photos).
