Beschreibung :

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 dBand 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 nstrumentation by maintaining a tight match of internal resistors and amplifiers.
