Product Summary

The LTC2495CUHF is a 16-channel (eight differential) , 16-bit, No Latency ΔΣADC with Easy Drive technology and a 2-wire, I2C interface. The LTC2495CUHF includes programmable gain, a high accuracy temperature sensor, and an integrated oscillator. The LTC2495CUHF allows a wide common mode input range (0V to VCC) , independent of the reference voltage. Applications of the LTC2495CUHF include: Direct Sensor Digitizer, Direct Temperature Measurement, Instrumentation and Industrial Process Control.
