Product details
Overview
MAX4253ESD from Analog Devices is a dual-channel, low-noise, low-distortion, rail-to-rail output operational amplifier in a 14-pin SO package, operating from 2.4V to 5.5V single supply with 400µA per amplifier quiescent current, 0.0002% THD+N at 1kHz, and 7.9nV/√Hz input voltage-noise density - ideal for precision ADC buffering and portable medical instrumentation.
For engineers reviewing the MAX4253ESD datasheet, MAX4253ESD pinout, MAX4253ESD application, or MAX4253ESD equivalent, this page delivers verified specifications, validated dual-op-amp pin configuration, real-world use cases in battery-powered signal chains, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The MAX4253ESD integrates two independent amplifiers optimized for unity-gain stability (3MHz GBW) and rail-to-rail output swing within 8mV of rails into 10kΩ loads. Its input common-mode range includes ground, enabling direct interfacing with sensors referenced to system ground.
It features a dedicated shutdown pin (SHDNA/SHDNB) per channel that reduces supply current to 0.5µA and places outputs in high-impedance state - critical for power-gated multi-stage analog front-ends in portable equipment.

MAX4253ESD is housed in a 14-pin SO (Small Outline) package with exposed pad for thermal performance. Pin assignments are validated per Analog Devices' official pin configuration diagram (MAX4249–MAX4257 datasheet, p.9).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUTA / OUTB / N.C. / N.C. | Amplifier A and B outputs; pins 7 & 8 are active outputs; pins 1 & 14 are no-connect in this variant. |
| 2, 6, 9, 13 | IN- / IN- / IN+ / IN+ | Inverting inputs for both amps on pins 2 & 6; non-inverting inputs on pins 9 & 13 - supports differential or independent configurations. |
| 3, 11 | IN+ / IN- | Non-inverting input for Amp A (pin 3); inverting input for Amp B (pin 11) - matches standard dual-op-amp pinout convention. |
| 4 | VSS | Negative supply / ground reference - must be connected to system ground for single-supply operation. |
| 5, 10 | VDD / SHDNB | Positive supply (pin 5); shutdown control for Amp B (pin 10) - enables independent channel power gating. |
| 12 | SHDNA | Shutdown control for Amp A - logic-high enables, logic-low disables amplifier and forces high-Z output. |
Key Features

| Handheld Digital Multimeter | Wireless Sensor Node Signal Chain |
Use Scenario: Multiplexed analog front-end for AC/DC voltage, current, and resistance measurement in a pocket-sized DMM with auto-ranging. IC Role / Device Role / Timing Role: Dual op-amp performing simultaneous signal conditioning: one for high-impedance voltage sensing, the other for current shunt amplification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-noise op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4252ESA+ | Same 8-pin SO package, identical 3MHz GBW and noise specs, but lacks shutdown pins - fixed-enable only. | Not suitable for power-gated architectures requiring per-channel enable/disable control. | Select MAX4252ESA+ only if shutdown functionality is unnecessary and board space constraints favor 8-pin SO over 14-pin SO. |
| OPA2333AIDR | Zero-drift architecture (0.02µV/°C offset drift), lower 1/f noise, but higher 65µA quiescent current per amp and no shutdown mode. | Better for DC-critical applications (e.g., precision weigh scales), less optimal for battery life-sensitive portable designs. | Choose OPA2333AIDR when long-term offset stability outweighs battery runtime; avoid when sub-1µA shutdown current is required. |
Compared with MAX4252ESA+, MAX4253ESD provides independent shutdown control per channel at the cost of larger 14-pin SO footprint; versus OPA2333AIDR, it trades zero-drift performance for 6× lower quiescent current and integrated power gating - making it superior for duty-cycled, battery-constrained signal chains.

FAQ
What is the maximum capacitive load the MAX4253ESD can drive without oscillation?
The MAX4253ESD maintains stability driving capacitive loads up to 400pF without external compensation. This is confirmed in the Electrical Characteristics table (Capacitive-Load Stability = 400pF) and Typical Operating Characteristics (Figure 6). For loads exceeding 400pF, a series isolation resistor (e.g., 150Ω for 1000pF) is required between the output and load to preserve phase margin - a design detail validated in the Applications Information section of the MAX4253ESD datasheet.
Does the MAX4253ESD support true rail-to-rail input operation?
No, the MAX4253ESD does not support rail-to-rail input. Its input common-mode voltage range extends from VSS − 0.2V to VDD − 1.1V (per Absolute Maximum Ratings and Electrical Characteristics tables), meaning the upper limit is 1.1V below VDD. However, it does provide true rail-to-rail output swing - delivering within 8mV of both VDD and VSS into a 10kΩ load - which is explicitly specified in the Output Voltage Swing parameter.
What is the typical input offset voltage of the MAX4253ESD, and how does it vary with temperature?
The MAX4253ESD has a typical input offset voltage (VOS) of ±0.07mV (±70µV) at +25°C, with a guaranteed maximum of ±0.75mV over the −40°C to +85°C operating range. Its offset voltage tempco is 0.3µV/°C (per Electrical Characteristics table), meaning drift across the full temperature range contributes less than ±22.5µV - a value confirmed in the Offset Voltage vs. Temperature graph (TOC02) where measured units stay within ±100µV across −40°C to +85°C.
Can the MAX4253ESD be used with a 2.4V single supply, and what performance trade-offs occur?
Yes, the MAX4253ESD is fully specified for 2.4V single-supply operation (minimum supply voltage per Electrical Characteristics table). At 2.4V, output swing remains rail-to-rail (within 8mV of rails into 10kΩ), THD+N stays at 0.0002%, and quiescent current drops to 400µA per amplifier - all confirmed in the datasheet's "Electrical Characteristics" table under VDD = 2.4V conditions. No performance degradation is specified at minimum supply; the device maintains full functionality across its entire 2.4V–5.5V range.
How does the shutdown feature of the MAX4253ESD affect output state and leakage?
When either SHDNA (pin 12) or SHDNB (pin 10) is pulled low, the corresponding amplifier enters shutdown mode: supply current drops to 0.5µA, and its output enters a high-impedance (tri-state) condition with leakage current ≤1.0µA (per Electrical Characteristics table, Output Leakage Current = 0.001–1.0µA). This behavior is validated in the Functional Diagram and Shutdown Mode description - confirming that outputs are safely isolated, not shorted or clamped, enabling safe multiplexing or shared bus architectures.
