TPC6240数据手册3PEAK中文资料规格书

描述 Description

TPC6240 is a precision 8-/16-channel, multiplexed ADC with integrated PGA and many other features, offering accurate measurement for low-bandwidth input signals, and lower-system cost and component count.

The device has a 24-bit delta-sigma converter, with configurable data rates. There are sinc5 filter for optimized nosie performance, and low-latency filter for fast settling with 50-/60-Hz rejection for noisy industrial environments.

A low-noise programmable gain amplifer provides 1~128 gain options to amplify low-level signals.

Additionaly, it integrates a precision 2.5-V band gap reference and integrated oscillator.

Two programmable exitation current souces are available for easy RTD biasing for temperature measurement.

Finally, more features such as burn out, CRC, voltage bias, system monitoring, and GPIOs are integrated.

The device is available in QFN6X6-40 package.
