The LTC®2310-14 is a low noise, high speed 14-bit +
sign successive approximation register (SAR) ADC with
differential inputs and wide input common mode range.
Operating from a single 3.3V or 5V supply, the LTC2310-14
has an 8VP-P differential input range, making it ideal for
applications which require a wide dynamic range with
high common mode rejection. The LTC2310-14 achieves
±2.5LSB INL guaranteed, no missing codes at 14 bits and
82dB SNR typical.
The LTC2310-14 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
LTC2310-14 also has a high speed SPI-compatible serial
interface that supports CMOS or LVDS. The fast 2Msps
throughput with no cycle latency makes the LTC2310-14
ideally suited for a wide variety of high speed applications.
The LTC2310-14 dissipates only 35mW with a 5V supply
and offers nap and sleep modes to reduce the power
consumption for further power savings during inactive
periods.
