Product details
Overview
MAX4253EUB-T from Analog Devices is a dual-channel, low-noise, low-distortion, rail-to-rail output operational amplifier in a 10-pin µMAX package, featuring 3MHz gain-bandwidth product, 400µA quiescent current per amplifier, and shutdown mode reducing supply current to 0.5µA - ideal for portable instrumentation and ADC buffer applications operating from 2.4V to 5.5V single supply.
For engineers reviewing the MAX4253EUB-T datasheet, MAX4253EUB-T pinout, MAX4253EUB-T application, or MAX4253EUB-T equivalent, key selection criteria include its unity-gain stability, 8mV rail-to-rail output swing with 10kΩ load, input common-mode range extending to ground, THD+N of 0.0004% at 1kHz, and confirmed 400pF capacitive-load stability without external compensation.
Technical Context
The MAX4253EUB-T belongs to the MAX4250–MAX4254 subgroup, which is unity-gain stable (GBW = 3MHz) and optimized for precision, low-power, single-supply operation. Its input stage supports common-mode voltage down to VSS − 0.2V and up to VDD − 1.1V, enabling ground-sensing capability in battery-powered systems.
It integrates two independent amplifiers sharing a single shutdown control (SHDNA/SHDNB), placing both outputs in high-impedance state when SHDN is pulled low. The device drives 1kΩ loads while maintaining DC accuracy and handles capacitive loads up to 400pF without oscillation - critical for driving ADC inputs and sensor signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 3MHz - ensures stable unity-gain operation and sufficient bandwidth for audio and sensor signal conditioning up to ~100kHz closed-loop. |
| Quiescent Supply Current | 400µA per amplifier - enables multi-day battery life in portable medical or handheld test equipment. |
| Input Offset Voltage | ±0.07mV (typ) - minimizes DC error in precision gain stages and bridge sensor interfaces. |
| Output Swing (vs. Rails) | Within 8mV at 10kΩ load - maximizes dynamic range in low-voltage (e.g., 3.3V or 2.4V) data acquisition systems. |
| Total Harmonic Distortion + Noise | 0.0004% at 1kHz, 1kΩ load - preserves signal fidelity in 16-bit ADC front-ends and audio preamplifiers. |
| Capacitive-Load Drive | 400pF - eliminates need for isolation resistors when driving SAR ADC inputs or long PCB traces. |
| Input Bias Current | 0.1pA (typ) - enables accurate amplification of high-impedance sources like piezoelectric sensors or pH electrodes. |
Pinout & Package
MAX4253EUB-T is housed in a 10-pin µMAX package (3mm × 3mm, 0.5mm pitch), thermally enhanced with exposed paddle. Pinout is fully validated per Analog Devices' official pin configuration diagram for MAX4253 (10-pin µMAX variant).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - rail-to-rail capable, high-impedance in shutdown mode. |
| 2 | VDD | Positive supply (2.4V–5.5V) - requires local 0.1µF ceramic bypass to ground. |
| 3 | OUTB | Amplifier B output - independently buffered, same specs as OUTA. |
| 4 | INA− | Inverting input for Amp A - matched impedance critical for THD optimization. |
| 5 | INB− | Inverting input for Amp B - electrically isolated from INA−; no crosstalk in layout. |
| 6 | INB+ | Noninverting input for Amp B - supports ground-referenced sensor inputs. |
| 7 | VSS | Negative supply / ground - return path for all currents; must be low-impedance. |
| 8 | INA+ | Noninverting input for Amp A - identical DC specs and noise performance as INB+. |
| 9 | SHDN | Shutdown control (active-low) - pulls both outputs to high-Z; logic thresholds at 0.2×VDD / 0.8×VDD. |
| 10 | NC | No connection - not internally bonded; leave unconnected or grounded per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 8mV of VDD/VSS at 10kΩ - preserves >99% of full-scale ADC input range at 3.3V supply. |
| Ground-sensing input | Common-mode range includes VSS − 0.2V - enables direct interfacing to 0V-referenced transducers without level-shifting. |
| Low-power shutdown | Reduces total supply current to ≤1.0µA (both amps) - extends shelf life and enables duty-cycled sensing. |
| 400pF capacitive-load stability | No external compensation required - simplifies layout for ADC driver and filter applications. |
| Ultra-low input bias current | 0.1pA typical - avoids voltage errors in high-Z source applications (e.g., photodiode TIA feedback networks). |
Applications
| Portable Medical Sensors | 16-bit ADC Input Buffer |

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 |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture (0.02µV/°C VOS drift); higher IQ (17µA); 350kHz GBW | Better DC precision over temperature; lower bandwidth limits AC signal fidelity | Select for ultra-stable DC gain stages where THD < 0.001% is secondary to offset drift. |
| AD8602ARZ-REEL7 | Higher GBW (10MHz); higher IQ (800µA); no shutdown; SO-8 package | Superior speed for active filters; higher power disqualifies battery-critical designs | Select when driving high-speed ADCs or requiring >1MHz closed-loop bandwidth with no shutdown requirement. |
Compared with OPA2333AIDR and AD8602ARZ-REEL7, the MAX4253EUB-T uniquely balances micropower operation (400µA), rail-to-rail output, shutdown capability, and 3MHz bandwidth - making it optimal for space-constrained, battery-operated precision analog front-ends where power, size, and AC performance must coexist.

FAQ
What is the operating temperature range for the MAX4253EUB-T?
The MAX4253EUB-T is specified for operation from –40°C to +85°C, matching the commercial/industrial grade qualification of the MAX4250–MAX4254 subgroup. It is not rated for automotive (–40°C to +125°C) use - that specification applies only to the MAX4250AAUK variant. Thermal derating begins above +70°C, with power dissipation reduced at 5.6mW/°C.
Does the MAX4253EUB-T support true rail-to-rail input operation?
No - the MAX4253EUB-T features rail-to-rail *output* operation but has a limited input common-mode range: guaranteed from VSS − 0.2V to VDD − 1.1V. While this includes ground (VSS), it does not extend to VDD. For full rail-to-rail input, consider alternatives like the ADA4661-2. The MAX4253EUB-T's input stage is optimized for ground-referenced sources, not high-side sensing.
Can the MAX4253EUB-T drive a 1000pF capacitive load?
Not stably without external compensation. The MAX4253EUB-T is characterized for stable operation up to 400pF. For 1000pF loads (e.g., long cables or large ADC input capacitance), an isolation resistor (e.g., 150Ω) must be placed in series with the output, as documented in Analog Devices' Application Note. Failure to do so risks peaking or oscillation, especially at gains ≥ 10V/V.
What is the shutdown behavior of the MAX4253EUB-T?
When SHDN (Pin 9) is pulled low (≤0.2×VDD), both amplifiers enter shutdown: supply current drops to ≤1.0µA total, and both outputs (OUTA and OUTB) enter high-impedance state. The delay to enable is 8µs (MAX4251/MAX4253), and delay to shutdown is 0.8µs. Input pins remain high-impedance during shutdown, preserving source integrity.
Is the MAX4253EUB-T pin-compatible with other devices in the MAX4249–MAX4257 family?
Yes - the MAX4253EUB-T (10-pin µMAX) shares identical pinout with the MAX4253ESD+ (14-pin SO) and MAX4253EBC+T (10-bump UCSP) variants. All three part numbers map Pin 1→OUTA, Pin 2→VDD, Pin 3→OUTB, etc., per the official Pin/Bump Configuration table. This allows drop-in replacement across package types without PCB redesign.
