Product details
Overview
MAX4252EBL-T from Analog Devices is a dual, single-supply, rail-to-rail output operational amplifier optimized for low-noise (7.9nV/√Hz at 30kHz), low-distortion (0.0004% THD+N at 1kHz), and ultra-low quiescent current (400µA per amplifier) operation from 2.4V to 5.5V. It features unity-gain stability, 3MHz gain-bandwidth product, and 8mV rail-to-rail output swing with 10kΩ load - ideal for portable instrumentation and ADC buffer stages in battery-powered systems.
For engineers reviewing the MAX4252EBL-T datasheet, MAX4252EBL-T pinout, MAX4252EBL-T application, or MAX4252EBL-T equivalent, key selection criteria include its UCSP-8 package footprint, guaranteed ground-sensing input (VCM includes VSS), 400pF capacitive-load drive capability, and absence of shutdown functionality - distinguishing it from MAX4251/MAX4256 variants.
Technical Context
The MAX4252EBL-T belongs to the MAX4249–MAX4257 family of precision op amps designed for wide-dynamic-range signal conditioning. It uses a fully differential input stage with picoampere-level input bias current (1pA typ) and achieves excellent DC accuracy (70µV VOS, 116dB large-signal voltage gain) while maintaining rail-to-rail output swing within 8mV of supplies.
Unlike decompensated members (e.g., MAX4256), the MAX4252EBL-T is unity-gain stable with 3MHz GBW and 0.3V/µs slew rate - optimized for low-frequency precision applications requiring stability without external compensation. Its 8-bump UCSP package enables high-density layout while preserving thermal performance (derate 4.7mW/°C above +70°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.4V to 5.5V - supports direct Li-ion or 3.3V system rail operation without level-shifting. |
| Quiescent Current | 400µA per amplifier - enables >10-year battery life in always-on sensor front-ends. |
| Input Offset Voltage | ±70µV max - ensures <1 LSB error when buffering 16-bit ADCs with 5V full-scale range. |
| Gain-Bandwidth Product | 3MHz - sufficient for anti-aliasing filters up to ~300kHz with unity-gain configuration. |
| Output Swing (10kΩ) | VDD − 8mV / VSS + 7mV - delivers full dynamic range in 2.4V-supply systems with minimal headroom loss. |
| Input Voltage Noise Density | 7.9nV/√Hz at 30kHz - preserves SNR in audio and medical sensor amplification paths. |
| Capacitive Load Drive | 400pF - eliminates need for isolation resistors in most PCB trace and filter capacitor scenarios. |
Pinout & Package
MAX4252EBL-T is housed in an 8-bump, 1.5mm × 1.5mm UCSP™ package with bottom-side solder bumps. The package is RoHS-compliant and rated for −40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | OUTA | Amplifier A output - rail-to-rail capable, drives 1kΩ loads with <1mV DC error. |
| 2 (B1) | VDD | Positive supply - bypass with 0.1µF ceramic capacitor placed adjacent to bump. |
| 3 (C1) | OUTB | Amplifier B output - independently buffered; no crosstalk degradation below 70dB @ 1MHz. |
| 4 (A2) | INA− | Inverting input A - high-impedance node (1000GΩ); sensitive to stray capacitance; keep traces short. |
| 5 (C2) | INB− | Inverting input B - electrically isolated from INA−; enables dual-channel independent signal paths. |
| 6 (B4) | VSS | Negative supply - connect directly to ground plane; serves as reference for single-supply operation. |
| 7 (A3) | INA+ | Noninverting input A - common-mode range extends 200mV below VSS, enabling true ground-referenced sensing. |
| 8 (C3) | INB+ | Noninverting input B - identical specs to INA+; supports differential or independent single-ended configurations. |
Key Features
| Feature | Design Value |

| Rail-to-rail output swing | Within 8mV of VDD/VSS with 10kΩ load - maximizes usable dynamic range in low-voltage systems. |
| Ultra-low input voltage noise | 7.9nV/√Hz at 30kHz - critical for preserving resolution in piezoelectric transducer and strain gauge interfaces. |
| Ground-sensing input | VCM includes VSS (−0.2V min) - enables direct connection to 0V-referenced sensors without level-shifting circuitry. |
| Unity-gain stability | No external compensation required - simplifies design of buffers, active filters, and gain-of-1 signal conditioners. |
| 400pF capacitive load drive | Stable without isolation resistor - reduces BOM count and layout complexity in anti-aliasing filter implementations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual, rail-to-rail, low-noise op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4252ESA+ | SO-8 package (3.9mm × 4.9mm) vs. UCSP-8 (1.5mm × 1.5mm); same electrical specs and pinout. | Preferred where manual assembly, rework, or thermal mass requirements favor leaded packages. | Select MAX4252ESA+ when board-level test access or thermal dissipation >379mW is required. |
| OPA2333AIDR | Zero-drift architecture (0.02µV/°C VOS drift) vs. standard CMOS; higher IQ (17µA per amp); 350kHz GBW. | Better for DC-critical applications like precision weigh scales; unsuitable for >100kHz signal chains due to lower bandwidth. | Choose OPA2333AIDR only when VOS drift <0.1µV/°C is mandatory and bandwidth ≤350kHz suffices. |
Compared with MAX4252ESA+, the MAX4252EBL-T offers 75% smaller footprint and improved high-frequency PSRR; compared with OPA2333AIDR, it delivers 8.5× higher bandwidth and 23× lower quiescent current - making it optimal for portable, wideband, battery-constrained designs.

FAQ
What is the operating temperature range for the MAX4252EBL-T?
The MAX4252EBL-T is specified for operation from −40°C to +85°C. This industrial temperature range ensures reliable performance in portable instrumentation, field-deployed sensors, and consumer medical devices exposed to ambient thermal variation. The device's thermal derating (4.7mW/°C above +70°C) and guaranteed parameters across this range make it suitable for uncontrolled-environment deployments without additional thermal management.
Does the MAX4252EBL-T include a shutdown feature?
No, the MAX4252EBL-T does not include a shutdown input. Unlike MAX4251/MAX4256 variants, it lacks SHDN pins and operates continuously when powered. This simplifies layout and eliminates control logic overhead but means quiescent current remains fixed at 400µA per amplifier - appropriate for applications where duty cycling is managed externally or continuous operation is required.
Can the MAX4252EBL-T drive a 1kΩ load while maintaining rail-to-rail output swing?
Yes, the MAX4252EBL-T is characterized to drive 1kΩ loads with rail-to-rail output swing - though output voltage swing degrades to VDD − 77mV / VSS + 47mV under those conditions. For applications demanding minimal headroom loss (e.g., 2.4V-supply systems), a 10kΩ load is recommended to achieve the specified 8mV/7mV swing. The device maintains DC accuracy (gain error <0.1%) even at 1kΩ loading.
What is the input common-mode voltage range of the MAX4252EBL-T?
The MAX4252EBL-T features a ground-sensing input with an input common-mode voltage range extending from VSS − 0.2V to VDD − 1.1V. This allows direct interface with 0V-referenced sources such as bridge sensors, thermocouples, and single-ended transducers without level-shifting circuitry - a key enabler for simplified, low-component-count front-end designs in portable equipment.
Is the MAX4252EBL-T pin-compatible with other devices in the MAX4249–MAX4257 family?
The MAX4252EBL-T shares identical pin functions with MAX4252ESA+ and MAX4252EUA+ in the same dual-amplifier configuration, but is not pin-compatible with single-amplifier (e.g., MAX4250) or shutdown-enabled (e.g., MAX4256) variants. Its UCSP-8 bump map matches the µMAX/SO-8 pinout electrically, enabling drop-in replacement where package conversion is acceptable - however, rework and thermal validation are required due to differing thermal characteristics.
