MAXIM INTEGRATED / ANALOG DEVICES MAX191BCWG 12-bit analog-to-digital converter
The MAX191BCWG+ is a low-power, 12-bit successive approximation analog-to-digital converter (ADC) with internal reference and power-down features, housed in a 24-pin WSOIC package. It converts analog input signals into 12-bit digital outputs using a track/hold circuit. The device offers flexible control logic for easy interfacing with microprocessors, requiring only passive components for most applications. Notably, it does not need an external hold capacitor for the track/hold function. The ADC operates from a single or dual power supply, supporting ground-referenced bipolar inputs, with a supply voltage range of 4.75V to 5.25V. It functions across temperatures from 0°C to 70°C, with a minimum conversion time of 7.5 microseconds and a maximum acquisition time of 2 microseconds. The internal reference includes an adjustment input for system gain calibration—either an internal or external reference can be used. The device supports three interface modes: two 8-bit parallel modes and a serial mode compatible with SPI, QSPI, and MICROWIRE standards. Typical applications include signal processing, portable devices, electromechanical systems, automatic testing, and telecommunications. It features a low operating power of approximately 3mA, a power-down current of about 20 microamperes, an integral linearity of ±1 LSB, and differential nonlinearity of ±1 LSB. Performance metrics include a SINAD of 70dB and total harmonic distortion of -80dB at 1kHz input signal at 25°C, with a tested sampling rate of 100kSPS.
