ADI LTC2442IG#PBF

248k2，4差分，单端5V5V-40°C ~ 85°C

Overview

The LTC2442IG is an ultra high precision, variable speed, 24-bit ΔΣ™ ADC with integrated amplifier. The amplifier can be configured as a buffer for easy input drive of high impedance sensors. 1 part-per-million (ppm) linearity is achievable when the amplifier is configured in unity gain. External resistors can be used to set a gain for increased resolution of low level input signals. The positive and negative amplifier supply pins may be tied directly to VCC (4.5V to 5.5V) and GND or biased above VCC and below GND for rail-to-rail input signals.

Any combination of single-ended (up to 4 inputs) or differential (up to 2 inputs) can be selected with a common mode input range from ground to VCC. While operating in the 1X speed mode the first conversion following a new speed/resolution or channel selection is valid.
