description
The TLV1571/1578 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 device contains two on-chip control registers allowing
control of channel selection, software conversion start, and power down via the bidirectional parallel port. 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. Therefore, one signal conditioning
circuit can be used for all eight channels. The TLV1571 is a single channel analog input device with all the same
functions as the TLV1578.
The TLV1571/ TLV1578 operates from a single 2.7-V to 5.5-V power supply. It accepts an analog input range
from 0 V to AVDD and digitizes the input at a maximum 1.25 MSPS throughput rate at 5 V. The power dissipations
are only 12 mW with a 3-V supply or 35 mW with a 5-V supply. The device features an auto power down mode
that automatically powers down to 1 mA 50 ns after conversion is performed. In software power down mode, the
ADC is further powered down to only 10
A.
Very high throughput rate, simple parallel interface, and low power consumption make the TLV1571/ TLV1578
an ideal choice for high-speed digital signal processing requiring multiple analog inputs.
