12-bit, single-ended analog-to-digital converter (ADC) designed for resistive touchscreens. Features 2 analog inputs, 6 channels, and a unipolar polarity. Operates with a single supply voltage range of 1.6V to 3.6V, consuming a low 10nA operating supply current. Supports I2C, SPI, and 2-wire interfaces, with a sampling rate of 105 kS/s. Integral nonlinearity is 3 LSB, and full-scale error is 4 LSB. Packaged in tape and reel.
