GENERAL DESCRIPTION
The TC3402 is a low cost, low power analog-to-digital
converter based on Microchip’s Sigma-Delta technology. It
will perform 16-bit conversions (15-bit plus sign) at up to
eight per second. The TC3402 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.
The TC3402’s 2-wire MicroPortdigital 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 conver-
sion 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.
The TC3402 is available in 16-Pin PDIP and 16-Pin
QSOP packages.
