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 antialiasing
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
DD
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 autopower-down mode that automatically powers down to 300
uA, 10 ns after a conversion is performed. With software power down enabled, the device is
further powered down to only 10 uA.
The TLV1570 communicates with digital microprocessors via a simple 4- or 5-wire serial port
that interfaces directly to Texas Instruments TMS320 DSPs, and SPITM and QSPITM 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.
