Product Introduction

MAX7129 Low noise, 4 1/2-bit, monolithic ADC with multiplexed LCD driver

description

Maxim's ICL7129A/MAX7129 is a high-precision monolithic 4-1/2-digit A/D converter that directly drives a multiplexed liquid crystal display. Using a new "continuous integration" technology, 20,000 count resolutions are ± over the ICL7129A/MAX7129 2.00000V and 200.00mV ranges. It has a high impedance differential input, excellent differential linearity, true ratio operation, and automatic polarity. The only external active component that needs to be made with precise DVM/DPM is a reference. Over-range and under-output and 10:1 range change input convenient auto-regulating system design. ICL7129A/MAX7129 detects and flags the low voltage state of the battery, and also checks for continuity, giving a visual indication and logic level output that can be used to generate audio signals.

MAX7129 has 0.0005% full-scale accuracy, 10μV resolution, zero-read drift of 0.5μV/°C, input bias of 10pA maximum, and a flip error of less than 1 count. Maxim has reduced ICL7129A noise by 3μV significantly less than MAX7129.

Key features:

± 19,999 count resolution
Input bias current (MAX7129) up to 10pA
3μV peak-to-peak noise (ICL7129A)
The onboard complex LCD display drives 4-1/2 digits, 4 decimal points, and 3 digit alarms
Instant continuity detection
Battery low voltage detector and indicator
Over/underrange output
Precise 10:1 range selection
10μV resolution
Significantly improved ESD protection
Monolithic, low-power CMOS design
No need to compensate for capacitors
