Description

Programmable Data Rates: 2.5 SPS to 8 kSPS

Digital Filter: Simultaneous 50-Hz and 60-Hz

Rejection at ≤ 20 SPS with Low-Latency Digital

Filter

–

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.

Integrated Functions:

•

Dual-Matched Programmable Current Sources for

Sensor Excitation: 10 µA to 2000 µA

–

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.

Internal Reference: 2.5 V

–

Internal Oscillator

A low-noise programmable gain amplifer provides 1~128

gain options to amplify low-level signals.

Internal Temperature Sensor

Extended Fault Detection Circuits

Additionaly, it integrates a precision 2.5-V band gap

reference and integrated oscillator.

Self Offset and System Calibration

–

GPIO and GPO pins with external mux control

–

Two programmable exitation current souces are available

for easy RTD biasing for temperature measurement.

Digital Interface

•

3-/4- wire SPI-Compatible Interface with CRC

Checking

–

Finally, more features such as burn out, CRC, voltage bias,

system monitoring, and GPIOs are integrated.

Digital Supply: 2.7 V to 5 V

Package: 40-lead 6mm x 6 mm QFN

Operating Temperature: –40°C to +125°C

•

The device is available in QFN6X6-40 package.
