The LTC2320-16 is a low noise, high speed octal 16‑bit successive approximation register (SAR) ADC with differential inputs and wide input common mode range. Operating from a single 3.3V or 5V supply, the LTC2320-16 has an 8VP-P differential input range, making it ideal for applications which require a wide dynamic range with high common mode rejection. The LTC2320-16 achieves ±2LSB INL typical, no missing codes at 16 bits and 82dB SNR.
The LTC2320-16 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference. The LTC2320-16 also has a high speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 1.5Msps per channel throughput with no latency makes the LTC2320-16 ideally suited for a wide variety of high speed applications. The LTC2320-16 dissipates only 20mW per channel and offers nap and sleep modes to reduce the power consumption to 26μW for further power savings during inactive periods.

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
Demonstration circuit 2395A features the LTC®2325/ LTC2324/LTC2320 family. With up to 5Msps, these differential, multiple channel, 16-bit, serial, high speed successive approximation register (SAR) ADCs are available in a 52-lead QFN package. Each ADC has an internal 20ppm/°C maximum drift reference and an SPI-compatible serial interface that supports CMOS and LVDS logic. Note the demo board is configured for CMOS operation by default; see the note under JP8 for LVDS operation. The demo manual refers to the LTC2325, but applies to all members of the family, the only difference being the number of channels, the sample rate and/or the number of bits.
Software & Systems Requirements
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
