The LTC2442 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.The proprietary ΔΣ architecture ensures stable DC accuracy through continuous transparent calibration. Ten speed/resolution combinations from 6.9Hz/220nVRMS to 3.5kHz/25µVRMS can be selected with no latency or shift in DC accuracy. Additionally, a 2X speed mode can be selected enabling output rates up to 7kHz (8kHz with an external oscillator) with one cycle latency.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.
