ADS1146IPW Description

Short technical summary and product information.

The ADS1146IPW is a precision 16-bit sigma-delta ADC from Texas Instruments designed for sensor measurement applications. It offers a maximum sampling rate of 2 kSPS and includes a programmable gain amplifier (PGA) with gains from 1 V/V to 128 V/V. The device supports both differential and single-ended input configurations through a single input channel.

 

Key electrical specifications include an analog supply voltage range of 2.7 V to 5.25 V and a digital supply range of 2.7 V to 5.25 V. Typical power consumption is 2.3 mW. The ADC features an external reference, SPI data interface, and includes features such as 50/60 Hz rejection, internal oscillator, and temperature sensor. The operating temperature range is -40°C to 105°C.

 

The device is housed in a 16-pin TSSOP package (16-TSSOP, 4.40mm width) with surface mount mounting. The package has a footprint of 32 mm² (5 mm × 6.4 mm). The ADS1146IPW is part of the ADS114x family of precision ADCs and is suitable for applications requiring high-resolution conversion with low power consumption.
