BH45B1225

24-Bit A/D Peripheral

Features

General Description

• Wide operating voltage: 2.4V~5.5V

• Internal Programmable Gain Ampliﬁer

• Internal I²C interface for external communiation

• 5Hz~1.6kHz ADC output data rate

• Internal temperature sensor for compensation

• Package Types: 8-pin SOP/16-pin NSOP

The BH45B1225 is a multi-channel 24-bit Delta

Sigma A/D converter which includes a programmable

gain amplifier and is designed for applications that

interface diﬀerentially to analog signals. The device

has the benefits of low noise and high accuracy

and communicates with external hardware using an

internal I²C bus. This highly functionally integrated

Delta Sigma analog to digital converter with its

high accuracy and low power specifications offers a

superior solution for interfacing to external sensors

especially for battery powered applications.

Applications

• Instrumentation

• Health Monitoring Equipment

• Precision Sensing
