The LTC2328-16 is a low noise, high speed 16-bit successive approximation register (SAR) ADC with pseudo-differential inputs. Operating from a single 5V supply, the LTC2328-16 has a ±10.24V true bipolar input range, making it ideal for high voltage applications which require a wide dynamic range. The LTC2328-16 achieves ±1.5LSB INL maximum, no missing codes at 16 bits with 93.5dB SNR.

The LTC2328-16 has an on-board single-shot capable reference buffer and low drift (20ppm/°C max) 2.048V temperature compensated reference. The LTC2328-16 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 1Msps throughput with no cycle latency makes the LTC2328-16 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2328-16 dissipates only 50mW 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 LTC2328-16 to 300μW for further power savings during inactive periods.

Product Details

The LTC^®2338/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.
