ANALOG DEVICES LTC2338CMS-18#PBF Analogue to Digital Converter, 18 bit, 1 MSPS, Differential, SPI, Single, 4.75 V

LTC2338CMS-18#PBF is a low noise, high speed 18bit successive approximation register (SAR) ADC with fully differential inputs. Operating from a single 5V supply, the LTC2338-18 has a ±10.24V true bipolar input range, making it ideal for high voltage applications which require a wide dynamic range. The LTC2338-18 achieves ±4LSB INL maximum, no missing codes at 18bits with 100dB SNR. The LTC2338-18 has an onboard single-shot capable reference buffer and low drift (20ppm/°C max) 2.048V temperature compensated reference. The LTC2338-18 also has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisy-chain mode. The fast 1Msps throughput with no cycle latency makes the LTC2338-18 ideally suited for a wide variety of high speed applications. Applications include programmable logic controllers, industrial process control, high speed data acquisition, portable or compact instrumentation, ATE.
