GENERAL DESCRIPTION

The AD8253 is an instrumentation amplifier with digitally

programmable gains that has gigaohm (GΩ) input impedance,

low output noise, and low distortion, making it suitable for

interfacing with sensors and driving high sample rate analog-to-

digital converters (ADCs).

It has a high bandwidth of 10 MHz, low THD of −110 dB, and

fast settling time of 780 ns (maximum) to 0.001%. Offset drift and

gain drift are guaranteed to 1.2 μV/°C and 10 ppm/°C, respectively,

for G = 1000. In addition to its wide input common voltage range,

it boasts a high common-mode rejection of 100 dB at G = 1000

from dc to 20 kHz. The combination of precision dc performance

coupled with high speed capabilities makes the AD8253 an

excellent candidate for data acquisition. Furthermore, this

monolithic solution simplifies design and manufacturing and

boosts performance of instrumentation by maintaining a tight

match of internal resistors and amplifiers.

The AD8253 user interface consists of a parallel port that allows

users to set the gain in one of two different ways (see Figure 1

for the functional block diagram). A 2-bit word sent via a bus

The AD8253 is available in a 10-lead MSOP package and is

specified over the −40°C to +85°C temperature range, making it

an excellent solution for applications where size and packing

density are important considerations.

input. An alternative is to use

transparent gain mode, where the state of logic levels at the gain

port determines the gain.
