TLV1570CPWR

Product Summary

The TLV1570CPWR is a 2.7 v to 5.5 v 8-channel 10-bit 1.25-msps serial analog-to-digital converter. It is a 10-bit data acquisition system that combines an 8-channel input multiplexer (MUX), a high-speed 10-bit ADC, an on-chip reference, and a high-speed serial interface. The TLV1570CPWR contains an on-chip control register allowing control of channel selection, conversion start, reference voltage levels, and power down via the serial port. The MUX is independently accessible, which allows the user to insert a signal conditioning circuit such as an anti-aliasing filter or an amplifier, if required, between the MUX and the ADC. The applications of the TLV1570CPWR include: Mass Storage and Hard Disk Drive, Automotive, Digital Servos, Process Control, General Purpose DSP, Image Sensor Processing.
