The AD7152/AD7153 are 12-bit sigma-delta (Σ-Δ) capacitance-to-digitalconverters (CDCs). The capacitance to be measured isconnected directly to the device inputs. The architecture featuresinherent high resolution (12-bit no missing codes, up to 12-biteffective resolution) and high linearity (±0.05%). The AD7152/AD7153 have four capacitance input ranges per operation mode,±0.25 pF to ±2 pF in differential mode and 0.5 pF to 4 pF insingle-ended mode.
The AD7152/AD7153 can accept up to 5 pF common-modecapacitance (not changing), which can be balanced by aprogrammable on-chip, digital-to-capacitance converter(CAPDAC).
The AD7153 has one capacitance input channel, while theAD7152 has two channels. Each channel can be configuredas single-ended or differential. The AD7152/AD7153 aredesigned for floating capacitive sensors.
The AD7152/AD7153 have a 2-wire, I2C-compatible serialinterface. Both devices can operate with a single power supplyfrom 2.7 V to 3.6 V. They are specified over the temperaturerange of −40°C to +85°C and are available in a 10-lead MSOP.
