Description

The LTC2327-18 is a low noise, high speed 18-bit successive approximation register (SAR) ADC with pseudo-differential inputs. Operating from a single 5V supply, the LTC2327-18 has a ±10.24V true bipolar input range, making it ideal for high voltage applications which require a wide dynamic range. The LTC2327-18 achieves ±5LSB INL maximum, no missing codes at 18 bits with 95dB SNR.The LTC2327-18 has an onboard single-shot capable reference buffer and low drift (20ppm/°C max) 2.048V temperature compensated reference. The LTC2327-18 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 500ksps throughput with no cycle latency makes the LTC2327-18 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2327-18 dissipates only 36mW 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 LTC2327-18 to 300μW for further power savings during inactive periods.BitsLTC2327-1616LTC2327-1818ApplicationsProgrammable Logic ControllersIndustrial Process ControlHigh Speed Data AcquisitionPortable or Compact InstrumentationATE
