The TSC2003 is a classic Successive Approximation Register (SAR) analog-to-digital converter (ADC). The
architecture is based on capacitive redistribution which inherently includes a sample-and-hold function. The
converter is fabricated on a 0.6
CMOS process.
The basic operation of the TSC2003 is shown in Figure 3. The device features an internal 2.5-V reference and
an internal clock. Operation is maintained from a single supply of 2.7 V to 5.25 V. The internal reference can be
overdriven with an external, low-impedance source between 2 V and VDD. The value of the reference voltage
directly sets the input range of the converter.
The analog input (X, Y, and Z parallel coordinates, auxiliary inputs, battery voltage, and chip temperature) to the
converter is provided via a multiplexer. A unique configuration of low on-resistance switches allows an
unselected ADC input channel to provide power and an accompanying pin to provide ground for an external
device. By maintaining Figure 3, a differential input to the converter, and a differential reference architecture, it is
possible to negate the switch’s on-resistance error (should this be a source of error for the particular
measurement).
