MAX1494

description

MAX1492/MAX1494 low-power, 3.5 and 4.5 digital, analog-to-digital converter (ADC) integrated liquid crystal display (LCD) drivers operate from a single 2.7V to 5.25V supply. They include in-house references, high-precision on-chip oscillators, and triplexed LCD drivers. The internal charge pump generates negative power and requires an input buffer integrated with a single power supply supply. The ADC is configured to ± an input range of 2V or ±200mV and outputs its conversion results to an LCD and/or microcontroller (μC). μC communication is facilitated via SPI™-/QSPI™-/MICROWIRE-compatible® serial interfaces. MAX1492 is a 3.5-bit (±1999 count) device and MAX1494 is a 4.5-bit (±19,999 count) device.

The MAX1492/MAX1494 does not require external high-precision integrated capacitors, auto-zeroing capacitors, crystal oscillators, charge pumps, or other circuitry required for dual-slope ADCs (commonly used in panel instrumentation circuits).

The devices also feature on-chip buffers, and the differential signal and reference inputs allow for direct interfacing with high-impedance sources. In addition, they use continuous internal offset calibration and provide 50Hz synchronous rejection > 100dB and 60Hz supply noise. Other features include data hold, peak hold, overrange and under-detection, low battery monitor.

MAX1494 32-pin, 7 mm x 7 mm LQFP package and 28-pin SSOP and 28-pin PDIP package, MAX1492. All devices in this family operate over the 0°C to +70°C commercial temperature range.
