GENERAL DESCRIPTION
The AD8250 is an instrumentation amplifier with digitally
programmable gains that has G 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
sent via a bus can be latched using the WR input. An alternative is
to use the transparent gain mode where the state of the logic levels
at the gain port determines the gain.
