LTC2327-16 - 16-Bit, 500ksps, ±10.24V True Bipolar, Pseudo-Differential Input ADC with 93.5dB SNR
The LTC®2327-16 is a low noise, high speed 16-bit successive approximation register (SAR) ADC with pseudodifferential inputs. Operating from a single 5V supply, the LTC2327-16 has a ±10.24V true bipolar input range, making it ideal for high voltage applications which require a wide dynamic range. The LTC2327-16 achieves ±1.5LSB INL maximum, no missing codes at 16 bits with 93.5dB SNR.
The LTC2327-16 has an onboard single-shot capable reference buffer and low drift (20ppm/°C max) 2.048V temperature compensated reference. The LTC2327-16 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 500ksps throughput with no cycle latency makes the LTC2327-16 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2327-16 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 LTC2327-16 to 300μW for further power savings during inactive periods.
