DESCRIPTION
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. 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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not
apply when operating the device beyond its specified operating conditions.
(2) All voltages are measured with respect to the ground pins.
(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(4) When the input voltage (VIN) at any pin exceeds the power supply rails (VIN < Vor VIN > V+) the absolute value of the current at that pin
should be limited to 5 mA or less. The 20 mA package input current limits the number of pins that can exceed the power supply
boundaries with a 5 mA current limit to four.
(5) Human body model, 100 pF discharged through a 1.5 kΩ resistor.
