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 AV
DD
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 uA.
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.
