No Latency Delta Sigma ADCs

Analog Devices' family of No Latency Delta Sigma ADCs is unrivaled in performance and ease of use. Targeted for precision measurement applications, the family of ultralow noise ADCs offers sample rates from 6.8Hz up to 8kHz and the ability to select between 50Hz or 60Hz, or simultaneous, line frequency rejection. Unique features like the Easy Drive current cancellation technique enables external RC networks and high impedance sensors to directly interface to the Easy Drive ADC family without external amplifiers. If an external amplifier is used, the ADC automatically calibrates both the offset and drift of the circuit .
