Linear Technology's LTC2389-18 is a low noise, high speed 18-bit successive approximation register (SAR) ADC. Operating from a single 5 V supply, the LTC2389-18 supports pin-configurable fully differential (±4.096 V), pseudo-differential unipolar (0 V to 4.096 V), and pseudo-differential bipolar (±2.048 V) analog input ranges, allowing it to interface with multiple signal chain formats without requiring additional level translation or signal conditioning. The LTC2389-18 achieves ±3 LSB INL (maximum), no missing codes at 18-bits, and 99.8 dB (fully differential) / 95.2 dB (pseudo differential) SNR (typical).
