description
The TLV571 is an 8-bit data acquisition system
that combines a high-speed 8-bit ADC and a
parallel interface. The device contains two on-chip control registers allowing control of software conversion start
and power down via the bidirectional parallel port. The control registers can be set to a default mode using a
dummy RD while WR is tied low allowing the registers to be hardware configurable.
The TLV571 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 TLV571 an ideal
choice for high-speed digital signal processing.
