MS3110 - Universal Capacitive Readout CMOS

Description

The Universal Capacitive ReadoutTM IC (MS3110) is a general purpose, ultra-low noise CMOS IC intended to support a variety of MEMS sensors that require a high resolution capacitive readout interface.

The MS3110 requires only a single +5VDC supply and some decoupling components.

Features

Capacitance resolution: 4.0aF/rtHz.
Sensor modes: single variable or dual differential variable.
On-chip dummy capacitor for quasi-differential operation and initial adjustment.
Gain and DC offset trim.
Programmable bandwidth adjustment 0.5 to 8kHz (9 steps).
2.25VDC output for ADC reference/ratiometric operation.
Single supply of +5.0VDC.
On-chip EEPROM for storage of settings.
Available in die or 16-pin SOIC Ap.

MS3110 Universal Capacitive ReadoutTM IC Description: The Universal Capacitive ReadoutTM IC (MS3110) is a general purpose, ultra-low noise CMOS IC intended to support a variety of MEMS sensors that require a high resolution capacitive readout interface. The MS3110 requires only a single +5VDC supply and some decoupling components. No additional components are required. MEMS sensors (such as accelerometers, rate sensors, and other sensors that can be modeled as variable capacitors) require a readout electronic interface that can sense small changes in capacitance. The MS3110 is capable of sensing capacitance changes down to 4.0 aF/rtHz, typical. The MS3110 interfaces to either a differential capacitor pair or a single capacitive sensor.
