Analog Devices Inc. LTC238x-18 18-Bit SAR ADCs

Analog Devices Inc. LTC238x-18 are low noise, high speed, 18-bit successive approximation register (SAR) analog-to-digital converters (ADC) available in 5Msps, 10Msps, and 15Msps. The devices are ideally suited for a wide range of applications. The combination of excellent linearity and wide dynamic range makes the components ideal for high-speed imaging and instrumentation applications. No-latency operation provides a unique solution for high-speed control loop applications.

The low distortion at high input frequencies enables communications applications requiring wide dynamic range and significant signal bandwidth. To support high-speed operation while minimizing the number of data lines, the Analog Devices Inc. LTC238x-18 features a serial LVDS digital interface. The LVDS interface has one-lane and two-lane output modes, allowing the user to optimize the interface data rate for each application.
