20-Bit ADC Provides 15 Hz Output Rate

The LTC2435 20-bit A/D converter offers users a 15 Hz output rate with 50/60 Hz rejection and maintains a 2 ppm integral nonlinearity (INL) performance. It operates from a 2.7V to 5.5V supply, consuming 200 µA during conversion and 4 µA during shutdown, and accepts any differential reference voltage from 0.1V to VCC. Performing transparent, full-scale calibration on every conversion, the device ensuresstability of full-scale readings over time, changes in supply voltage, and over the it's temperature range. Other features include a 20-bit output with no missing codes, CMRR of 140 dB, and a noise figure of 4 µVRMS. The LTC2435 comes in a 16-pin SSOP priced at $3.55 each/1,000.
