PRODUCT DESCRIPTION

PRODUCT HIGHLIGHTS

The AD625 is a precision instrumentation amplifier specifically

designed to fulfill two major areas of application: 1) Circuits re-

quiring nonstandard gains (i.e., gains not easily achievable with

devices such as the AD524 and AD624). 2) Circuits requiring a

low cost, precision software programmable gain amplifier.

1. The AD625 affords up to 16-bit precision for user selected

fixed gains from 1 to 10,000. Any gain in this range can be

programmed by 3 external resistors.

2. A 12-bit software programmable gain amplifier can be config-

ured using the AD625, a CMOS multiplexer and a resistor

network. Unlike previous instrumentation amplifier designs,

the ON resistance of a CMOS switch does not affect the gain

accuracy.

For low noise, high CMRR, and low drift the AD625JN is the

most cost effective instrumentation amplifier solution available.

An additional three resistors allow the user to set any gain from

1 to 10,000. The error contribution of the AD625JN is less than

0.05% gain error and under 5 ppm/°C gain TC; performance

limitations are primarily determined by the external resistors.

Common-mode rejection is independent of the feedback resistor

matching.

3. The gain accuracy and gain temperature coefficient of the

amplifier circuit are primarily dependent on the user selected

external resistors.

4. The AD625 provides totally independent input and output

offset nulling terminals for high precision applications. This

minimizes the effects of offset voltage in gain-ranging

applications.

A software programmable gain amplifier (SPGA) can be config-

ured with the addition of a CMOS multiplexer (or other switch

network), and a suitable resistor network. Because the ON

resistance of the switches is removed from the signal path, an

AD625 based SPGA will deliver 12-bit precision, and can be

programmed for any set of gains between 1 and 10,000, with

completely user selected gain steps.

5. The proprietary design of the AD625 provides input voltage

noise of 4 nV/√Hz at 1 kHz.

6. External resistor matching is not required to maintain high

common-mode rejection.

For the highest precision the AD625C offers an input offset

voltage drift of less than 0.25 µV/°C, output offset drift below

15 µV/°C, and a maximum nonlinearity of 0.001% at G = 1. All

grades exhibit excellent ac performance; a 25 MHz gain band-

width product, 5 V/µs slew rate and 15 µs settling time.

The AD625 is available in three accuracy grades (A, B, C) for

industrial (–40°C to +85°C) temperature range, two grades (J,

K) for commercial (0°C to +70°C) temperature range, and one

(S) grade rated over the extended (–55°C to +125°C) tempera-

ture range.
