LTC2440 Datasheet (Linear Technology) - 24-Bit High Speed Differential delta-sigma ADC

LTC2440, 24-Bit High Speed Differential delta-sigma ADC

The LTC®2440 is a high speed 24-bit No Latency ∆∑TM ADC with 5ppm INL and 5µV offset.

It uses a proprietary delta-sigma architecture enabling variable speed and resolution with no latency.

Ten speed/resolution combinations (6.9Hz/200nVRMS to 3.5kHz/25µVRMS) are programmed through a simple serial int
