Analog Devices Inc. ADCMP609BRMZ-REEL7

Overview

ADCMP609BRMZ-REEL7 from Analog Devices is a rail-to-rail, single-supply comparator with TTL/CMOS-compatible outputs, 40 ns propagation delay, ±3 mV offset voltage, and programmable hysteresis - designed for high-speed threshold detection in instrumentation and clock restoration circuits operating from 2.5 V to 5.5 V.

For engineers reviewing the ADCMP609BRMZ-REEL7 datasheet, ADCMP609BRMZ-REEL7 pinout, ADCMP609BRMZ-REEL7 application, or ADCMP609BRMZ-REEL7 equivalent, key selection criteria include input common-mode range (−0.2 V to VCC + 0.2 V), shutdown capability, 15 pF load timing compliance, and hysteresis control via external resistor on HYS pin.

Technical Context

The ADCMP609BRMZ-REEL7 uses a dual-front-end input stage enabling rail-to-rail operation across −0.2 V to VCC + 0.2 V, with crossover bias points at ~0.8 V and ~1.6 V. Its internal gain stage delivers 80 dB active gain and 50 dB CMRR over full temperature range.

It integrates a TTL-/CMOS-compatible output driver capable of sourcing/sinking 0.8 mA while maintaining 25–50 ns rise/fall times, plus a dedicated shutdown pin (SDN) that reduces supply current to ≤260 µA and enables wake-up within 150 ns.

Key Specifications

FAQ

What is the absolute maximum input voltage rating for ADCMP609BRMZ-REEL7?

The ADCMP609BRMZ-REEL7 supports input voltages from −0.5 V to VCC + 0.5 V, with differential input voltage up to ±(VCC + 0.5 V). Exceeding these limits risks permanent damage. The device tolerates overdrive beyond its common-mode range (−0.2 V to VCC + 0.2 V) without phase reversal, but operation outside absolute max ratings is strictly prohibited per datasheet Table 2.

Does ADCMP609BRMZ-REEL7 require external hysteresis resistors to function?

No - ADCMP609BRMZ-REEL7 operates without external hysteresis components. Leaving the HYS pin open or driving it high disables hysteresis. A pull-down resistor (30–120 kΩ) adds controllable hysteresis (0.1–160 mV); no resistor is needed for basic comparator operation. The internal 1.25 V bias and 7 kΩ series resistance eliminate dependency on external feedback topology.

Can ADCMP609BRMZ-REEL7 operate from a single 2.5 V supply?

Yes - ADCMP609BRMZ-REEL7 is fully specified for single-supply operation from 2.5 V to 5.5 V. At 2.5 V, it delivers 40 ns propagation delay, 1 mW power dissipation, rail-to-rail input range (−0.2 V to +2.7 V), and TTL/CMOS-compatible outputs with VOH ≥ 2.1 V and VOL ≤ 0.4 V at 0.8 mA load.

What is the purpose of the VEE pin on ADCMP609BRMZ-REEL7?

The VEE pin (Pin 6) serves as the negative supply reference and is typically connected to ground in single-supply configurations. It enables true dual-supply operation (e.g., ±2.5 V) if required, but the ADCMP609BRMZ-REEL7's rail-to-rail input stage functions correctly with VEE = GND and VCC = 2.5–5.5 V - no negative supply is necessary for standard use cases.

How does the shutdown feature affect output state in ADCMP609BRMZ-REEL7?

When SDN is driven low, ADCMP609BRMZ-REEL7 enters shutdown mode with supply current reduced to ≤260 µA, and both Q and Q outputs enter high-impedance states - not logic-high or logic-low. This allows safe bus sharing or multi-comparator configurations without contention. Output drivers resume normal TTL/CMOS behavior within 150 ns after SDN returns high.
