ANALOG DEVICES LTC2326HMS-16#PBF Analogue to Digital Converter, 16 bit, 250 kSPS, Pseudo Differential, SPI, Single, 4.75 V

LTC2326HMS-16#PBF is a low noise, high speed 16bit successive approximation register (SAR) ADC with pseudo-differential inputs. Operating from a single 5V supply, the LTC2326-16 has a ±10.24V true bipolar input range, making it ideal for high-voltage applications that require a wide dynamic range. The LTC2326-16 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 250ksps throughput with no cycle latency makes the device ideally suited for a wide variety of high-speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2326-16 dissipates only 28mW and automatically naps between conversions, leading to reduced power dissipation that scales with the sampling rate. Applications include programmable logic controllers, industrial process control, high-speed data acquisition, portable or compact instrumentation, and ATE.
