The LTC®2452 is an ultra-tiny, fully differential, 16-bit, analog-to-digital converter. The LTC2452 uses a single 2.7V to 5.5V supply and communicates through an SPI interface. The ADC is available in an 8-pin, 3mm × 2mm DFNpackageorTSOT-23 package. Itincludesanintegrated oscillator that does not require any external components. It uses a delta-sigma modulator as a converter core and has no latency for multiplexed applications. The LTC2452 includes a proprietary input samplingscheme thatreduces the average input sampling current several orders of magnitude when compared to conventional delta-sigma converters. Additionally, due to its architecture, there is negligible current leakage between the input pins.
