The LTC2326-16 is a low noise, high speed 16-bit 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 which require a wide dynamic range. The LTC2326-16 achieves ±1.5LSB INL maximum, no missing codes at 16 bits with 93.5dB SNR.The LTC2326-16 has an on-board single-shot capable reference buffer and low drift (20ppm/°C max) 2.048V temperature compensated reference. The LTC2326-16 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 250ksps throughput with no cycle latency makes the LTC2326-16 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. A sleep mode is also provided to reduce the power consumption of the LTC2326-16 to 300μW for further power savings during inactive periods.BitsLTC2326-1616LTC2326-1818ApplicationsProgrammable Logic ControllersIndustrial Process ControlHigh Speed Data AcquisitionPortable or Compact InstrumentationATE
