Product Summary
The LTC2440CGN is a high speed 24-bit No Latency △∑ ADC with 5ppm INL and 5μV offset. It uses proprietary deltasigma architecture enabling variable speed and resolution with no latency. The LTC2440CGN combinations (6.9Hz/200nVRMS to 3.5kHz/25μVRMS) are programmed through a simple serial interface. Alternatively, by tying a single pin HIGH or LOW, a fast (880Hz/2μVRMS) or ultralow noise(6.9Hz, 200nVRMS, 50/60Hz rejection)speed/resolution combination can be easily selected. The applications of the LTC2440CGN include: High Speed Multiplexing, Weight Scales, Auto Ranging 6-Digit DVMs, Direct Temperature Measurement, High Speed Data Acquisition.
