DESCRIPTION
The ADS7843 is a 12-bit sampling analog-to-digital
converter (ADC) with a synchronous serial interface
and low on-resistance switches for driving touch
screens. Typical power dissipation is 750
μ
W at a
125kHz throughput rate and a +2.7V supply. The
reference voltage (V
) can be varied between 1V and
+V
, providing a corresponding input voltage range
of 0V to V
. The device includes a shutdown mode
which reduces typical power dissipation to under
0.5
μ
W. The ADS7843 is guaranteed down to 2.7V
operation.
Low power, high speed, and on-board switches make
the ADS7843 ideal for battery operated systems such
as personal digital assistants with resistive touch screens
and other portable equipment. The ADS7843 is avail-
able in a 16-lead SSOP package and is guaranteed
over the –40
°
C to +85
°
C temperature range.
