Expand the operating speed and precision of sensitive measurement instruments with the AD7190 sigma-delta, analog-to-digital converter. The converter achieves greater than true 16-bit noise-free resolution up to 2.4 kHz across all input voltages from 40 mV to 5 V. Users can achieve 21-bit noise-free resolution for high-precision dc systems and the single-chip solution performs accurate measurements across a broad range of input signal magnitudes and data rates. The converter features an on-chip programmable gain amplifier with ultra-low noise and drift from dc to 4.8 kHz, an oscillator, temperature sensor, bridge power-down switch, reference detect monitor, and pseudo-differential or fully differential input channels.
