The LTC2311-16 is a low noise, high speed 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 LTC2311- 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 LTC2311-16 achieves ±3LSB INL typical, no missing codes at 16 bits and 81dB SNR typical.

The LTC2311-16 has an onboard low drift (20ppm/°C max) 2.048V or 4.096V temperature-compensated reference and provides an external 1.25V buffered reference input. The LTC2311-16 also has a high speed SPI-compatible serial interface that supports CMOS or LVDS. The fast 5Msps throughput with one-cycle latency makes the LTC2311-16 ideally suited for a wide variety of high speed applications. The LTC2311-16 dissipates only 50mW with a 5V supply and offers nap and sleep modes to reduce the power consumption to 5μW for further power savings during inactive periods.

Product Detail

Demonstration circuit 2425A features the LTC2311 family. With up to 5Msps, these differential, single channel, 16-bit, serial, high speed successive approximation register (SAR) ADCs are available in a 16-lead MSOP package. The LTC2311 family 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 JP3 for LVDS operation. The demo manual refers to the LTC2311, but applies to all members of the family, the only difference being the sample rate and/or the number of bits.
