12-Bit Capacitance-to-Digital Converter

AD7152/AD7153

GENERAL DESCRIPTION

FEATURES

Capacitance-to-digital converters

Interfaces to floating sensors

The AD7152/AD7153 are 12-bit sigma-delta (Σ-Δ) capacitance-to-

digital converters (CDCs). The capacitance to be measured

Resolution down to 0.25 fF (that is, up to 12 ENOB)

Linearity: 0.05%

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 (±±.±5ꢀ).

The AD7152/AD7153 have four capacitance input ranges per

operation mode, ±±.25 pꢁ to ±2 pꢁ in differential mode and

±.5 pꢁ to 4 pꢁ in single-ended mode.

Common-mode (not changing) capacitance up to 5 pF

Four capacitance ranges selectable per operation mode

0.25 pF to 2 pF in differential mode

0.5 pF to 4 pF in single-ended mode

Tolerant of parasitic capacitance to ground up to 50 pF

Conversion time per channel: 5 ms, 20 ms, 50 ms, and 60 ms

Internal clock oscillator

The AD7152/AD7153 can accept up to 5 pꢁ common-mode

capacitance (not changing), which can be balanced by a

programmable on-chip, digital-to-capacitance converter

(CAPDAC).

2-wire serial interface (I²C-compatible)

Power

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.

2.7 V to 3.6 V single-supply operation

100 μA current consumption

Operating temperature: −40°C to +85°C

10-lead MSOP package

The AD7152/AD7153 have a 2-wire, I²C®-compatible serial

interface. Both parts can operate with a single power supply

from 2.7 V to 3.6 V. They are specified over the temperature

range of −4±°C to +85°C and are available in a 1±-lead MSOP

package.
