AD96685BRZ

The AD96685BRZ is an ultrafast voltage comparator from Analog Devices. It features a typical propagation delay of 2.5 ns and a delay dispersion of 50 ps, ensuring consistent timing performance across varying overdrive conditions. The device is designed for high-speed signal processing applications such as line receivers, threshold detectors, and peak detectors.

The comparator includes a level-sensitive latch input that enables tracking, track-hold, or sample-hold modes of operation. The outputs are complementary digital signals fully compatible with ECL 10K and 10KH logic families. They are open-emitter type and require external pull-down resistors, typically 50 Ω to -2 V for driving transmission lines.

Key electrical specifications include a maximum input offset voltage of 2 mV at 25°C and 3 mV over the full temperature range, with a typical input bias current of 10 µA. The common-mode input voltage range spans from -2.5 V to +5 V. The device operates from dual supplies of +5 V and -5.2 V, with a typical quiescent current of 18 mA per comparator. CMRR is 90 dB typical and PSRR is 70 dB typical.

The AD96685BRZ is offered in a 16-lead SOIC package with a surface-mount mounting type. It operates over an industrial temperature range of -25°C to +85°C. Power dissipation is 118 mW per comparator.
