- Part Number:
- MAX1492CAI T
- Manufacturer:
- Maxim Integrated
- Ventron No:
- 3252485-MAX1492CAI T
- Description:
- IC ADC W/LCD DRIVER 28-SSOP
- Datasheet:
- MAX1492CAI T
Description
The MAX1492/MAX1494 are low-power, 3.5- and 4.5-digit analog-to-digital converters (ADCs) with integrated liquid crystal display (LCD) drivers. They operate from a single 2.7V to 5.25V power supply and include an internal reference, a high-accuracy on-chip oscillator, and a triplexed LCD driver. An internal charge pump generates the negative supply needed to power the integrated input buffer for single-supply operation. The ADCs are configurable for either a ±2V or 200mV input range and output their conversion results to an LCD and/or to a microcontroller (UC). UC communication is facilitated through an SPI-/QSPI-/MICROWIRE®-compatible serial interface. The MAX1492 is a 3.5-digit (1999 count) device, and the MAX1494 is a 4.5-digit ( 19,999 count) device.
