TPC6240 is a precision 8-/16-channel, multiplexed ADCwith integrated PGA and many other features, offeringaccurate measurement for low-bandwidth input signals,and lower-system cost and component count.The device has a 24-bit delta-sigma converter, withconfigurable data rates. There are sinc5 filter for optimizednosie performance, and low-latency filter for fast settlingwith 50-/60-Hz rejection for noisy industrial environments.A low-noise programmable gain amplifer provides 1~128gain options to amplify low-level signals.Additionaly, it integrates a precision 2.5-V band gapreference and integrated oscillator.Two programmable exitation current souces are availablefor 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.
