High Dynamic Range DELTA-SIGMA MODULATOR
FEATURES DESCRIPTION
130d B DYNAMIC RANGE
The ADS1201 is a precision, 130d B dynamic range,
FULLY DIFFERENTIAL INPUT delta-sigma (∆Σ) modulator operating from a single
+5V supply. The differential inputs are ideal for direct
TWO-WIRE INTERFACE
connection to transducers or low level signals. With
INTERNAL/EXTERNAL REFERENCE
the appropriate digital filter and modulator rate, the
ON-CHIP SWITCHES FOR CALIBRATION
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
APPLICATIONS filter bandwidth of 1k Hz at a modulator rate of 320k Hz. INDUSTRIAL PROCESS CONTROL The ADS1201 is designed for use in high resolution
