LTC2386-16
16-Bit, 10Msps SAR ADC
Description
The LTC®2386-16 is a low noise, high speed, 16-bit 10Msps
successive approximation register (SAR) ADC ideally
suited for a wide range of applications. The combination
of excellent linearity and wide dynamic range makes the
LTC2386-16 ideal for high speed imaging and instru-
mentation applications. No-latency operation provides a
unique solution for high speed control loop applications.
The very 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 LTC2386-16 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.
