General Description
The TC3401 is a low cost, low power analog-to-digital
converter based on Microchip’s Sigma-Delta technol-
ogy. It will perform 16-bit conversions (15-bit plus sign)
at up to eight per second. The TC3401 is optimized for
use as a microcontroller peripheral in low cost, battery
operated systems. A voltage reference is included, or
an external reference can be used. A VDD monitor with
a reset generator provides Power-on Reset and Brown-
out protection while an extra threshold detector is suit-
able for use as an early warning Power Fail detector, or
as a Wake-up Timer.
The TC3401’s 2-wire microPort digital interface is
used for starting conversions and for reading out the
data. Driving the SCLK line low starts a conversion.
After the conversion starts, each additional falling edge
(up to six) detected on SCLK for t4 seconds reduces
the A/D resolution by one bit and cuts conversion time
in half. After a conversion is completed, clocking the
SCLK line puts the MSB through LSB of the resulting
data word onto the SDAT line, much like a shift register.
The part automatically sleeps when not performing a
data conversion.
