Introduction

The LTC2450 is a 16-bit, single-ended input, delta-sigma ADC in a 2mm × 2mm DFN package, but don’t let its small size and low cost fool you. The LTC2450 has impressive DC specs, including 2 LSB INL, 2 LSB offset and a 0.01% gain error, making it a perfect match for many high-end industrial sensors, as well as a wide variety of data acquisition, measurement, control and general purpose voltage monitoring applications.
