GENERAL DESCRIPTION
The AD7152/AD7153 are 12-bit sigma-delta (Σ-Δ) capacitance-to-
digital converters (CDCs). The capacitance to be measured is
connected directly to the device inputs. The architecture features
inherent high resolution (12-bit no missing codes, up to 12-bit
effective 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 in
single-ended mode.
The AD7152/AD7153 can accept up to 5 pF common-mode
capacitance (not changing), which can be balanced by a
programmable on-chip, digital-to-capacitance converter
(CAPDAC).
The AD7153 has one capacitance input channel, while the
AD7152 has two channels. Each channel can be configured
as single-ended or differential. The AD7152/AD7153 are
designed for floating capacitive sensors.
The AD7152/AD7153 have a 2-wire, I2C-compatible serial
interface. Both devices can operate with a single power supply
from 2.7 V to 3.6 V. They are specified over the temperature
range of −40°C to +85°C and are available in a 10-lead MSOP.
