Maxim MAX191BENG+

12100k1Псевдодифференциальный±5 В, 5 В5V-40°C ~ 85°C

Overview

The MAX191BENG is a monolithic, CMOS, 12-bit analog-to-digital converter (ADC) featuring differential inputs, track/hold (T/H), internal voltage reference, internal or external clock, and parallel or serial μP interface. The MAX191BENG has a 7.5μs conversion time, a 2μs acquisition time, and a guaranteed 100ksps sample rate. The MAX191BENG operates from a single +5V supply or from dual ±5V supplies, allowing ground-referenced bipolar input signals. The device features a logic power-down input, which reduces the 3mA VDD supply current to 50μA max, including the internal-reference current. Decoupling capacitors are the only external components needed for the power supply and reference. This ADC operates with either an external reference, or an internal reference that features an adjustment input for trimming system gain errors. The MAX191BENG provides three interface modes: two 8-bit parallel modes, and a serial interface mode that is compatible with SPI, QSPI, and MICROWIRE serial-interface standards.
