2. Explanation

The LTC2311CMSE-14 is a low-noise, high-speed, 14-bit signed bit successive approximation register (SAR) ADC with differential input and wide input common-mode range. The LTC2311CMSE-14 adopts a single 3.3V or 5V working power supply and has an 8VP-P differential input range, making it highly suitable for applications that require a wide dynamic range and high common-mode rejection. The LTC2311CMSE-14 achieved ±0.75LSB INL (typical value), no missed code (at 14 bits), and 80dB SNR (typical value).

The LTC2311CMSE-14 has a built-in low-drift (maximum value of 20ppm/°C) 2.048V or 4.096V temperature-compensated reference, and provides an external 1.25V buffered reference input. In addition, the LTC2311CMSE-14 also has a high-speed SPI-compatible serial interface that supports CMOS or LVDS. The high throughput rate of 5Msps and the single-cycle delay characteristics make the LTC2311CMSE-14 an ideal choice for numerous high-speed applications. The LTC2311CMSE-14 consumes only 50mW of power when using a 5V power supply and provides dozing and sleeping modes to reduce power consumption to 5μW, thereby achieving the purpose of further power saving during standby.
