description

The TLV1570 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 device 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.

Therefore one signal conditioning circuit can be used for all eight channels.

The TLV1570 operates from a single 2.7-V to 5.5-V power supply. The device accepts an analog input range

from 0 V to AV

and digitizes the input at a maximum 1.25 MSPS throughput rate. Power dissipation is only

8 mW with a 2.7-V supply or 40 mW with a 5.5-V supply. The device features an auto-power down mode that

automatically powers down to 300 µA, 10 ns after a conversion is performed. With software power down

enabled, the device is further powered down to only 10 µA.

The TLV1570 communicates with digital microprocessors via a simple 4- or 5-wire serial port that interfaces

directly to Texas Instruments TMS320 DSPs, and SPI and QSPI compatible microcontrollers without using

additional glue logic.

A very high throughput rate, a simple serial interface, and low power consumption make the TLV1570 an ideal

choice for high-speed digital signal processing requiring multiple analog inputs.
