Texas Instruments ADC0848
The ADC0844 and ADC0848 are CMOS 8-bit successive approximation A/D converters with versatile analog input multiplexers. The 4-channel or 8-channel multiplexers can be software configured for single-ended, differential or pseudo-differential modes of operation. The differential mode provides low frequency input common mode rejection and allows offsetting the analog range of the converter.FEATURES
1●2 Easy Interface to All Microprocessors

● Internal Clock
● 0V to 5V Input Range with Single 5V Power Supply
● Standard Width 20-Pin or 24-Pin PDIP
● 28 Pin PLCC Package KEY SPECIFICATIONS
● Resolution: 8 Bits
● Total Unadjusted Error: ±½ LSB and ± 1 LSB
● Single Supply: 5 VDC
● Low Power: 15 mW
● Conversion Time: 40 μs
DESCRIPTION
In addition, the A/D's reference can be adjusted enabling the conversion of reduced analog ranges with 8-bit resolution. The A/Ds are designed to operate from the control bus of a wide variety of microprocessors. TRI-STATE output latches that directly drive the data bus permit the A/Ds to be configured as memory locations or I/O devices to the microprocessor with no interface logic necessary.
