TLV1578IDA

Product Summary

The TLV1578IDA is a 10-bit data acquisition system that combines an 8-channel input multiplexer (MUX), a high-speed 10-bit ADC, and a parallel interface. The TLV1578IDA contains two on-chip control registers allowing control of channel selection, software conversion start, and power down via the bidirectional parallel port. The control registers can be set to a default mode by applying a dummy RD signal when WR is tied low. This allows the TLV1578IDA to be configured by hardware. The MUX is independently accessible. This allows the user to insert a signal conditioning circuit such as an antialiasing filter or an amplifier, if required, between the MUX and the ADC. The applications of the TLV1578IDA include Mass Storage and HDD, Automotive, Digital Servos, Process Control, General-Purpose DSP, Image Sensor Processing.
