ADC0841
8-Bit µP Compatible A/D Converter
General Description
The ADC0841 is a CMOS 8-bit successive approximation
A/D converter. Differential inputs provide low frequency input
common mode rejection and allow offsetting the analog
range of the converter. In addition, the reference input can
be adjusted enabling the conversion of reduced analog
ranges with 8-bit resolution.
The A/D is designed to operate with the control bus of a va-
riety of microprocessors. TRI-STATE® output latches that di-
rectly drive the data bus permit the A/D to be configured as
a memory location or I/O device to the microprocessor with
no interface logic necessary.
