The LTC2327-16 is a low noise, high speed 16-bit successive approximation register (SAR) ADC with pseudo-differential inputs. Operating from a single 5V supply, the 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 on-board 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.

Product Detail

The LTC2338/LTC2337/LTC2336/LTC2328/LTC2327/LTC2326 are true bipolar, low power, low noise ADCs with serial outputs that can operate from a single 5V supply. The demo manual refers to the LTC2338-18 but applies to all parts in the family, the only difference being the maximum sample rates and the number of bits. The LTC2338-18 supports a ±20.48V fully differential input range with a 100dB SNR, consumes only 50mW and achieves ±4LSB INL max with no missing codes at 18 bits. The DC1908A demonstrates the DC and AC performance of the LTC2338‑18 in conjunction with the DC590 QuikEval and DC718 PScope data collection boards.
