Analog Devices Inc./Maxim Integrated MAX9201EUE

Overview

MAX9201EUE from Maxim Integrated is a quad high-speed voltage comparator with TTL outputs, no output latches, 7ns typical propagation delay at 5mV overdrive, ±5V or +5V single-supply operation, and 9mW per comparator power consumption. It serves in high-speed A/D converter front-ends, line receivers, and signal restoration circuits where precise timing and rail-to-rail input sensing are required.

For engineers reviewing the MAX9201EUE datasheet, MAX9201EUE pinout, MAX9201EUE application, or MAX9201EUE equivalent, this page delivers verified electrical parameters, TSSOP-16 package mapping, functional role in mixed-signal sampling systems, and validated alternative comparators for fast decision-making in data-acquisition and timing-critical designs.

Technical Context

The MAX9201EUE implements four independent bipolar comparators with separate analog (VCC/VEE) and digital (VDD) supply domains, enabling noise isolation in mixed-signal environments. Its input common-mode range extends to the negative rail (VEE), supporting ground-referenced sensing under single +5V supply (VEE = GND).

All four channels feature active internal TTL pullups, deliver 3.0V–3.5V VOH at 1mA source, and sink 8mA while maintaining VOL ≤ 0.4V. Unlike MAX9202/MAX9203, it omits latch inputs-ensuring transparent, real-time response without hold functionality.

Key Specifications

Pinout & Package

MAX9201EUE is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package) with exposed pad, 0.65mm pitch, and JEDEC MO-153 compliant footprint. Pin 1 marked by dot; pins 3 and 6 share GND and VEE functions respectively for analog/digital domain separation.

FAQ

What is the maximum analog supply voltage range supported by the MAX9201EUE?

The MAX9201EUE supports an analog supply voltage range of VCC − VEE = +4.75V to +10.5V, allowing configurations such as ±5V (VCC = +5V, VEE = −5V), +10V single-ended (VEE = GND), or +5V single-ended (VEE = GND). This flexibility enables use in both split-rail and single-supply systems without redesigning the power architecture. The MAX9201EUE maintains full specification compliance across this entire range.

Does the MAX9201EUE include output latches like the MAX9202/MAX9203?

No, the MAX9201EUE does not include output latches. Unlike the MAX9202EUD and MAX9203EKA-T, which feature TTL-compatible latch inputs (LATCHA/LATCHB or LATCH), the MAX9201EUE provides fully transparent comparator operation-outputs respond immediately to input changes with no hold or sample-and-hold capability. This makes the MAX9201EUE ideal for real-time decision paths where latency must be minimized and deterministic.

What is the input common-mode voltage range of the MAX9201EUE, and why does it matter for single-supply operation?

The MAX9201EUE features an input common-mode voltage range extending from VEE − 0.1V to VCC − 2.25V. When operated from a single +5V supply (VEE = GND), this allows inputs to swing from 0V up to +2.75V-enabling direct sensing of ground-referenced signals such as sensor outputs or DAC voltages without level-shifting. This rail-to-rail input capability is essential for maximizing dynamic range in low-voltage embedded systems using the MAX9201EUE.

How does the MAX9201EUE achieve 7ns propagation delay while consuming only 9mW per comparator?

The MAX9201EUE achieves 7ns propagation delay at 9mW per comparator through optimized bipolar process design and tightly controlled internal gain-bandwidth trade-offs. Its 348-transistor layout balances speed and power by minimizing parasitic capacitance in critical signal paths and using efficient current-steering output stages. This combination delivers industry-leading speed-per-watt performance-40% faster and 50% more power-efficient than the legacy MAX901 family-without sacrificing input accuracy or noise immunity in the MAX9201EUE.

Can the MAX9201EUE operate with different analog and digital supply voltages, and how are they configured?

Yes, the MAX9201EUE supports independent analog (VCC/VEE) and digital (VDD) supplies: VCC − VEE ranges from +4.75V to +10.5V, while VDD must be +4.75V to +5.25V. This allows analog sections to run at ±5V for wide dynamic range while digital outputs interface cleanly with +5V TTL logic. Decoupling capacitors must be placed separately on VCC, VEE, and VDD pins to prevent coupling noise-critical for maintaining the MAX9201EUE's 7ns timing accuracy in mixed-signal environments.
