High Dynamic Range DELTA-SIGMA MODULATOR
Features q q q q q 130dB DYNAMIC RANGE FULLY DIFFERENTIAL INPUT TWO-WIRE INTERFACE INTERNAL/EXTERNAL REFERENCE ON-CHIP SWITCHES FOR CALIBRATION
DESCRIPTION
The ADS1201 is a precision, 130dB dynamic range, delta-sigma (∆Σ) modulator operating from a single +5V supply. The differential inputs are ideal for direct connection to transducers or low level signals. With the appropriate digital filter and modulator rate, the device can be used to achieve 24-bit analog-to-digital (A/D) conversion with no missing codes. Effective resolution of 20 bits can be maintained with a digital filter bandwidth of 1kHz at a modulator rate of...
