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
control registers can be set to a default mode by applying a dummy RD signal when WR is tied low. This allows
the TLV1571/1578 to be configured by hardware. 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.
