14-bit, single-supply analog-to-digital converter (ADC) featuring a true bipolar input. Achieves a 200 kS/s sampling rate with a 78 dB signal-to-noise ratio. Operates from a single 5V supply, consuming 20mW typical power. Offers a serial 2-wire SPI interface and a fast 4.5 µs conversion time. Integral nonlinearity is 2 LSB, with differential nonlinearity at -1 LSB. Packaged in an 8-pin R-style package with tin, matte contact plating.
