General Description

The TC3403 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 TC3403 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

suitable for use as an early warning Power Fail

detector, or as a Wake-up Timer.

The TC3403’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.

The TC3403 is available in a 16-Pin PDIP and a 16-Pin

QSOP package.
