Analog Devices Inc./Maxim Integrated MAX9012ESA+

Overview

MAX9012ESA+ from Maxim Integrated is a dual, high-speed, single-supply comparator IC with TTL-compatible outputs, 5ns typical propagation delay, ±5.5mV input offset voltage (max), and operation from 4.5V to 5.5V. It features stable linear-region behavior without oscillation, input range extending 200mV below ground, and is designed for precision timing and signal conditioning in space-constrained industrial and test equipment.

For engineers reviewing the MAX9012ESA+ datasheet, MAX9012ESA+ pinout, MAX9012ESA+ application, or MAX9012ESA+ equivalent, this page delivers verified electrical parameters, SO package mechanical data, dual-channel timing behavior, latch-free architecture, and real-world use context for high-speed zero-crossing detection, pulse discrimination, and sampling circuits.

Technical Context

The MAX9012ESA+ uses a bipolar process with fully differential input amplifiers and no built-in hysteresis, enabling resolution of low-overdrive signals without output instability. Its common-mode input range spans –0.2V to (VCC – 1.9V), supporting rail-to-rail input operation down to –200mV with respect to ground.

Each channel operates independently with matched propagation delays (ΔtPD(ch–ch) ≤ 500ps), 3ns rise/fall times, and TTL-level outputs capable of sinking 4mA at 0.6V or sourcing 4mA at 2.4V (VCC = 4.5V). Power supply rejection ratio is 63dB min, and input noise density is 6nV/√Hz at 100kHz.

Key Specifications

Pinout & Package

MAX9012ESA+ is housed in an 8-pin SO (Small Outline) package with standard 1.27mm pitch, JEDEC MS-012AC compliant, and rated for –40°C to +85°C operation.

FAQ

What is the maximum operating temperature range for the MAX9012ESA+?

The MAX9012ESA+ is specified for continuous operation from –40°C to +85°C ambient temperature. This extended temperature range is guaranteed per the datasheet's Absolute Maximum Ratings and Electrical Characteristics tables, making the MAX9012ESA+ suitable for industrial control, automotive under-hood sensing, and outdoor instrumentation environments where thermal stability is critical.

Does the MAX9012ESA+ include a latch function like the MAX9011 or MAX9013?

No, the MAX9012ESA+ does not include a latch enable (LE) input. Unlike the MAX9011 and MAX9013, which feature TTL-compatible latch functionality, the MAX9012ESA+ is a latch-free dual comparator. Its pinout omits LE and N.C., dedicating all eight pins to power, ground, two independent input pairs, and two TTL outputs-ensuring minimal latency and deterministic timing behavior.

Can the MAX9012ESA+ accept input voltages below ground, and how far?

Yes, the MAX9012ESA+ supports common-mode input voltages down to –0.2V (200mV below ground) without output phase reversal or damage. This is explicitly confirmed in the Electrical Characteristics table under "Common-Mode Input Voltage Range" and reinforced in the Detailed Description section, enabling direct interfacing with AC-coupled or bipolar sensor outputs without external level-shifting circuitry.

What is the typical propagation delay of the MAX9012ESA+, and under what conditions is it measured?

The typical propagation delay of the MAX9012ESA+ is 5ns, measured with C_L = 5pF, V_OD = 100mV, and V_CC = 5V at T_A = +25°C. This value applies to both rising and falling edges (t_PD+/t_PD−) and is validated across the full operating temperature range (–40°C to +85°C), where delay remains ≤10ns under worst-case conditions per the datasheet's Electrical Characteristics table.

Is the MAX9012ESA+ pin-compatible with other devices in the MAX9010–MAX9013 family?

No, the MAX9012ESA+ is not pin-compatible with the single-channel MAX9010/MAX9011/MAX9013 variants due to its dual-channel configuration and absence of latch or complementary output pins. However, within the dual-channel subset, the MAX9012ESA+ shares identical 8-pin SO pinout with the MAX9012EUA, differing only in package type (SO vs. µMAX) and marking-ensuring drop-in replacement between those two variants.
