MTA8252 轨对轨运放可替代HTC8522

The MTI8252 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 785 ns
(maximum) to 0.001%. Offset drift and gain drift are
guaranteed to 1.8 μV/°C and 10 ppm/°C,
respectively, for G = 8. 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 MTI 8251 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 MTI 8252 user interface consists of a
parallel port that a
