A pair of ±10 V, 16-bit analog-to-digital converters (ADC) combine a low-power successive approximation (SAR) ADC with sample and hold, clock, reference, and serial data interface. The devices’ high integration enables design in portable data acquisition and medical instrumentation. The first converter is specified at ±1.5 LSB maximum integral nonlinearity (INL), ±1.0 LSB maximum differential nonlinearity (DNL) at 16 bits, and has a 250 kHz sampling rate and flexible input ranges which can be configured for ±10 V, ±5 V, 0-4 V, or 0-8 V. The second offers excellent DC performance of ±2.0 LSB maximum INL and -1/+2 LSB maximum DNL.
