DESCRIPTION
OFFSET: 250µV (max)
DRIFT: 1µV/°C
The OPA827 series of JFET operational amplifiers

combines outstanding dc precision with excellent ac
performance. It offers 100µV of offset, very low drift
(1µV/°C) over temperature, low bias currents, and very low
flicker noise of 400nVPP (0.1Hz to 10Hz). It operates over
a very wide supply voltage range of 4V to 18V on a low
4.5mA supply current. A dual version is also available for
the OPA827 family.
LOW NOISE: 4.5nV//Hz at 1kHz
BANDWIDTH: 18MHz
SLEW RATE: 22V/µs
BIAS CURRENT: 3pA
QUIESCENT CURRENT: 4.5mA/Ch
WIDE SUPPLY RANGE: +4V to +18V
SINGLE PACKAGES: MSOP-8, SO-8
DUAL PACKAGES: TSSOP-8, SO-8
Excellent ac characteristics, such as 18MHz gain
bandwidth (GBW) and 22V/µs slew rate, and precision dc
characteristics make the OPA827 series well-suited for a
wide range of applications such as 16- to 18-bit data
acquisition systems, transimpedance (I/V−conversion)

ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.

functional operation of the device at these or any other conditions
beyond those specified is not supported.

Input terminals are diode-clamped to the power-supply rails.
Input signals that can swing more than 0.7V beyond the supply
rails should be current-limited to 10mA or less.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
