ADS1209 Datasheet Delta-Sigma Modulator

Manufacturer: Texas Instruments

Overview: ADS1209 www.ti.com Two 1-Bit, 10MHz, 2nd-Order Delta-Sigma Modulators Check for Samples: ADS1209 SBAS491 – FEBRUARY.

General Description

The ADS1209 is a two-channel, high-performance, delta-sigma (ΔΣ) modulator with an 86dB dynamic range, operating from a single +5V supply.

The differential inputs are ideal for direct connection to signal sources in an industrial environment.

With the appropriate digital filter and modulator rate, the device can be used to achieve 16-bit analog-to-digital (A/D) conversion with no missing codes.
