LTC2320HUKG-16#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2320HUKG-16#TRPBF is an octal, 16-bit successive approximation register (SAR) analog-to-digital converter with simultaneous sampling capabilities. It operates from a single 3.3V or 5V supply and features an 8V P-P differential input range. The device achieves ±2LSB typical integral nonlinearity, guarantees 16-bit resolution without missing codes, and delivers an 82dB signal-to-noise ratio at 500kHz. It includes low-drift internal references of 2.048V or 4.096V and supports high-speed SPI-compatible serial interfaces in CMOS or LVDS modes. Power consumption is 20mW per channel, with nap and sleep modes reducing usage to 26μW.

Analog To Digital Converters (ADC) FAQ

What is the maximum sampling frequency?

The maximum sampling frequency is 1.5 Msps per channel.

How does the SDR/DDR pin affect data output?

Tying SDR/DDR to GND enables Single Data Rate mode, shifting data on the falling edge of SCK. Tying it to OVDD enables Double Data Rate mode, shifting data on each SCK edge.

What is the function of the REFBUFEN pin?

The REFBUFEN pin disables the internal reference buffers when grounded, allowing external voltage references to drive the REFOUT pins.
