Product details
Overview
The MAX913ESA+TG002 from Maxim Integrated is a single, ultra-fast, low-power precision TTL comparator with differential inputs and complementary TTL outputs, 10ns typical propagation delay, ±5V or +5V single-supply operation, and stable linear-region behavior-ideal for high-speed switching regulators and V/F converters in industrial and embedded power systems.
For engineers reviewing the MAX913ESA+TG002 datasheet, MAX913ESA+TG002 pinout, MAX913ESA+TG002 application, or MAX913ESA+TG002 equivalent, key selection considerations include input common-mode range extending below negative rail (–0.2V to +3.5V on +5V supply), latch-enable functionality, 0.8mV offset voltage, and SO-8 packaging for space-constrained PCB layouts.
Technical Context
The MAX913ESA+TG002 employs a fully differential bipolar input amplifier with trimmed offset voltage (<2mV at +25°C) and no built-in hysteresis, enabling high-resolution detection of slow-moving or low-amplitude signals without oscillation in the linear region. Its latch-enable (LE) pin provides transparent or latched output control independent of input slew rate.
It operates from either ±5V supplies (common-mode input range –5.2V to +3.5V) or a single +5V supply (–0.2V to +3.5V), with V+ powering both analog and digital sections while V– powers only the analog stage. Output stages deliver TTL-compatible VOH ≥2.4V (IOUT = 10mA) and VOL ≤0.5V (ISINK = 10mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 10ns typ (ΔVIN = 100mV, VOD = 20mV); enables >85MHz signal discrimination in timing-critical sampling circuits. |
| Input Offset Voltage | 0.8mV max at +25°C; ensures accurate zero-crossing detection with sub-millivolt resolution. |
| Supply Current | 6mA per comparator at +5V; supports battery-powered or thermally constrained designs. |
| Input Common-Mode Range | –0.2V to +3.5V on +5V supply; allows direct interfacing with ground-referenced sensors or DACs. |
| Output Type | Complementary TTL (Q/Q̄); drives standard logic loads without level-shifting or external pull-ups. |
| Latch Enable Function | LE pin controls transparency/latching; eliminates need for external D-latches in synchronized sampling applications. |
| Operating Temperature | –40°C to +85°C; qualified for industrial-grade reliability in harsh ambient environments. |
Pinout & Package
MAX913ESA+TG002 is housed in an 8-pin SO (Small Outline) package (JEDEC MS-012, 150-mil width), measuring 4.9mm × 3.9mm × 1.75mm, with gull-wing leads and Pb-free finish compliant with RoHS.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply input (+5V or +4.5V to +5.5V); powers analog and digital sections; requires local 0.1µF ceramic bypass. |
| 2 | IN+ | Noninverting input; accepts signals within full common-mode range; high-impedance node (IB ≤ 8µA). |
| 3 | IN− | Inverting input; differential pair partner to IN+; enables threshold comparison with precise hysteresis-free operation. |
| 4 | V− | Negative supply (–5V or GND); powers analog section only; must be bypassed if used as split rail. |
| 5 | LE | Latch enable: high/floating → latched output; low → transparent mode; TTL-compatible logic interface. |
| 6 | GND | Logic ground reference; connects to system ground plane; critical for noise immunity and stable biasing. |
| 7 | Q | TTL output (active-high); sinks up to 10mA; compatible with 74LS/74F logic families. |
| 8 | Q̄ | Complementary TTL output (active-low); provides inverted logic state; eliminates need for external inverters. |
Key Features
| Feature | Design Value |
|---|---|
| No linear-region oscillation | Enables reliable zero-crossing detection on slow triangle/sine waves without added hysteresis or resolution loss. |
| Input range extends below negative rail | Supports ground-referenced inputs on single +5V supply (down to –0.2V), simplifying sensor interface design. |
| 10ns propagation delay | Meets timing budgets in high-frequency switching regulators and Ethernet line receivers up to 85MHz. |
| 6mA supply current per comparator | Reduces thermal load and power budget in multi-channel or portable systems versus legacy comparators. |
| Latch-enable with no minimum slew rate | Allows deterministic sampling of low-slew-rate signals (e.g., thermocouple outputs) without timing uncertainty. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1016CS8#PBF | Slower (20ns typ), higher supply current (8mA), narrower input common-mode range (–3.5V to +3.5V on ±5V). | Lacks latch-enable function; requires external latch for synchronized sampling. | Preferred where legacy footprint compatibility is required but lower speed and higher power are acceptable. |
| LM360M/NOPB | Higher offset (2mV), no latch, 25ns propagation delay, wider supply range (±15V), no negative-rail input capability. | Designed for general-purpose analog comparators; unsuitable for single-supply zero-crossing or latch-based sampling. | Consider only for non-critical, wide-supply applications where latch and rail-to-rail input are not needed. |
Compared with LT1016CS8#PBF and LM360M/NOPB, the MAX913ESA+TG002 delivers superior speed, lower power, rail-extended input range, and integrated latch control-making it the optimal choice for modern industrial timing, power control, and synchronized acquisition systems requiring deterministic, low-jitter decision-making.

FAQ
What is the maximum operating supply voltage for MAX913ESA+TG002?
The MAX913ESA+TG002 supports a positive supply voltage (V+) up to +7V and a negative supply voltage (V−) down to –7V, with absolute maximum V+ to V− differential of +13V. For reliable operation, use +5V (±5% tolerance) or ±5V supplies as specified in the electrical characteristics table; exceeding these limits risks permanent damage.
Does MAX913ESA+TG002 require external hysteresis for stable operation?
No, the MAX913ESA+TG002 does not require external hysteresis. Its unique internal design prevents oscillation in the linear region, allowing stable operation even with slow-moving or low-overdrive input signals. Adding hysteresis degrades resolution and is explicitly discouraged in the datasheet for highest accuracy applications.
Can MAX913ESA+TG002 operate from a single +5V supply?
Yes, the MAX913ESA+TG002 operates from a single +5V supply: connect V− to GND, and use V+ = +5V. In this configuration, the input common-mode range is –0.2V to +3.5V, supporting ground-referenced inputs. The device draws 6mA total supply current and delivers full TTL output swing.
What is the function of the LE pin on MAX913ESA+TG002?
The LE (Latch Enable) pin on MAX913ESA+TG002 controls output transparency: when LE is low, Q and Q̄ follow the input differential voltage in real time; when LE is high or floating, the outputs hold their last valid state. This enables synchronous sampling without external latches, and no minimum input slew rate is required for valid latching.
Is MAX913ESA+TG002 pin-compatible with other packages in the MAX913 family?
No, MAX913ESA+TG002 (SO-8) is not pin-compatible with MAX913EPA (PDIP-8) or MAX913EUA (µMAX-8), though all share identical pin functions. Pin numbering and physical layout differ across packages: SO-8 follows JEDEC MS-012, µMAX uses a 3mm × 3mm leadless outline, and PDIP has wider lead spacing. PCB layout must match the specific package variant ordered.
