LTC2385-16 16-Bit, 5Msps SAR ADC
FEATURES DESCRIPTION
n
5Msps Throughput Rate
The LTC®2385-16 is a low noise, high speed, 16-bit 5Msps n
No Pipeline Delay, No Cycle Latency
successive approximation register (SAR) ADC ideally n
93.8dB SNR (Typ) at fIN = 1MHz
suited for a wide range of applications. The combination n
101dB SFDR (Typ) at fIN = 1MHz
of excellent linearity and wide dynamic range makes the n
Nyquist Sampling Up to 2.5MHz Input
LTC2385-16 ideal for high speed imaging and instru- n Guaranteed 16-Bit, No Missing Codes mentation applications. No-latency operation provides a n ±0.5LSB INL (Max) unique solution for high speed control loop applications. n 8.192VP-P Differential Inputs The very low distortion at high input frequencies enables n 5V and 2.5V Supplies communications applications requiring wide dynamic n Internal 20ppm/°C (Max) Reference range and significant signal bandwidth. n Serial LVDS Interface To support high speed operation while minimizing the n 78mW Power Dissipation number of data lines, the LTC2385-16 features a serial n 32-Pin (5mm × 5mm) QFN Package LVDS digital interface. The LVDS interface has one-lane and two-lane output modes, allowing the user to optimize
