Maxim Integrated MAX138EPL
- Part Number:
- MAX138EPL
- Manufacturer:
- Maxim Integrated
- Ventron No:
- 3007298-MAX138EPL
- Description:
- IC ADC 3 1/2DIG W/LCD DVR 40-DIP
- Datasheet:
- MAX138EPL
Description
The MAX138/MAX139 are 3½ digit A/D converters (ADCs) with on-board LCD (MAX138) and LED (MAX139) display drivers. They also contain a charge-pump voltage inverter, allowing them to measure both positive and negative input voltages while operating from a single power-supply voltage from 2.5V to 7V. The operating circuits of the MAX138/MAX139 are similar to those of the ICL7136 and ICL7137 respectively, except the MAX138/MAX139 have an internal oscillator and an external charge-pump capacitor connected to pins 38 and 40.
MAX140 is a low segment-current version of the MAX139 intended for use with low-current LED displays.
Features
Single Supply 2.5V to 7.0V Operation
Measures Both Positive and Negative Input Voltages
Charge-Pump Voltage Inverter Generates a Negative Supply Voltage
Internal Bandgap Reference
On-Board Display Driver
Low Segment Current (MAX140)
Applications
5V Powered Panel Meters
3V Powered DMMs
Instruments
Portable Monitors
Weigh Scales
Digital Thermometers
