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 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 AVDD 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
A, 10 ns after a conversion is performed. With software power down
enabled, the device is further powered down to only 10
A.
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.
