MAX149

description

Los controladores de pantalla de cristal líquido (LCD) integrados de convertidor analógico a digital (ADC) MAX1492/MAX1494 de baja potencia, 3,5 y 4,5 digitales, funcionan con una sola fuente de alimentación de 2,7 V a 5,25 V. They include an internal reference, a high-precision on-chip oscillator, and a triplexed LCD driver. La generación de suministros negativos de la bomba de carga interna requiere un búfer de entrada integrado para la operación de suministro único. El ADC está configurado para un rango de entrada de ±2V o ±200mV y emite su conversión a cristal líquido y/o microcontrolador (μC). LA COMUNICACIÓN ΜC SE FACILITA A TRAVÉS DE UNA INTERFAZ SERIE COMPATIBLE CON® SPI/QSPI/™™ MICROCABLES. El MAX1492 es un dispositivo de 3,5 bits (±1999-count) y el MAX1494 es un dispositivo de 4,5 bits (±19.999-count).

Los MAX1492/MAX1494 no requieren condensadores integrados de precisión externa, condensadores autocero, osciladores de cristal, bombas de carga u otros circuitos necesarios para los ADC de doble pendiente comúnmente utilizados en circuitos de instrumentación de panel.

The devices also feature on-chip buffers, differential signals, and reference inputs that allow direct interfacing with high impedance signal sources. Además, utilizan una calibración interna continua de compensación y proporcionan un rechazo síncrono de 50Hz de > ruido de fuente de alimentación de 100dB y 60Hz. Otras características incluyen retención de datos, retención de pico, detección de sobrerango y rango inferior, monitor de batería baja.

El MAX1494 está disponible en el paquete LQFP MAX1494 de 32 pines, 7 mm x 7 mm y en los paquetes SSOP y PDIP de 28 pines, el MAX1492. All devices in this family operate over the 0°C to +70°C commercial temperature range.
