41/2 Digit LCD/ Single-Chip A/D Converter

4-1/2 Digit Single-Chip
A/D Converter with LCD Driver
- General Description
The Maxim lCL7129A/MAX7129 is a high precision
monolithic 4-1/2 digit A/D converter that directly drives
a multiplexed liquid crystal display. Using a novel
"successive integration" technique, the |CL7129A/
MAX7129 has a 1-20,000 count resolution on both
2.00000V and 200.00mV ranges. It features high impe-
dance differential inputs, excellent differential linearity,
true ratiometric operation and auto polarity. The only
external active component required to make precision
DVM/DPMs is a reference. The overrange and under-
range outputs and the 10:1 range changing input
facilitate the design of autoranging systems. The
|CL7129A/MAX7129 detects and flags a LOW BATTERY
condition and also checks for continuity, giving a
visual indication and a logic level output which can
be used to generate an audible signal.
The MAX7129 has a fullscale accuracy of O.0005%,
resolution of 10pV, zero reading drift of 0.5pV/°C.
an input bias of 10pA max, and a rollover error of
