GENERAL DESCRIPTION

The AD8250 is an instrumentation amplifier with digitally

programmable gains that has 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 615 ns (maximum) to 0.001%. Offset

drift and gain drift are guaranteed to 1.7 μV/°C and 10 ppm/°C,

respectively, for G = 10. In addition to its wide input common

voltage range, it boasts a high common-mode rejection of 80 dB

at G = 1 from dc to 50 kHz. The combination of precision dc

performance coupled with high speed capabilities makes the

AD8250 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 AD8250 user interface consists of a parallel port that allows

users to set the gain in one of two ways (see Figure 1). A 2-bit word

The AD8250 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 the transparent gain mode where the state of the logic levels

at the gain port determines the gain.
