This document introduces a Rail-to-Rail, fast, low power, single-supply TTL/CMOS comparator product. The product is suitable for applications such as high-speed instrumentation, clock and data signal restoration, logic level shifting or translation, high-speed line receivers, threshold detection, and peak and zero-crossing detection.
The ADCMP608 and ADCMP609 are single‑supply TTL/CMOS comparators fabricated on Analog Devices' XFCB2 process. They offer rail‑to‑rail operation from 2.5 V to 5.5 V, low glitch output stages, and a single‑pin control for programmable hysteresis and latch functions. The devices support a wide input range and include a shutdown pin for power saving.
Key features include a 30 ns propagation delay, 1 mW power consumption at 2.5 V, input common‑mode range from –0.2 V to VCC + 0.2 V, and a power‑supply rejection ratio greater than 60 dB. The ADCMP608 is offered in a 6‑lead SC70 package, while the ADCMP609 comes in an 8‑lead MSOP package, both with shutdown capability.
| Propagation Delay | 30 ns |
|---|---|
| Power Consumption | 1 mW at 2.5 V |
