Product details
Overview
MAX4253EBC+T from Analog Devices is a dual-channel, low-noise, low-distortion, rail-to-rail output operational amplifier in a 10-bump UCSP package, featuring 3MHz gain-bandwidth product, 400µA quiescent current per amplifier, and shutdown mode reducing supply current to 0.5µA. It operates from 2.4V to 5.5V single supply, supports ground-sensing inputs, and drives 1kΩ loads with ±5mA output capability - ideal for portable instrumentation and ADC buffer stages.
For engineers reviewing the MAX4253EBC+T datasheet, MAX4253EBC+T pinout, MAX4253EBC+T application, or MAX4253EBC+T equivalent, key selection criteria include its dual-channel UCSP footprint, guaranteed rail-to-rail output swing within 8mV of rails (10kΩ load), THD+N of 0.0004% at 1kHz, input voltage-noise density of 7.9nV/√Hz at 30kHz, and explicit support for capacitive-load stability up to 400pF without external compensation.
Technical Context
The MAX4253EBC+T belongs to the unity-gain stable subgroup (MAX4250–MAX4254) of the MAX4249–MAX4257 family, confirmed by its 3MHz GBW and stable operation at AV = 1V/V. Its input common-mode range extends from –0.2V to VDD – 1.1V, enabling true ground-sensing functionality, while the push-pull output stage delivers rail-to-rail swing with <25mV headroom under 10kΩ load.
It integrates dual independent amplifiers sharing one shutdown control (SHDNA/SHDNB), each with 11pF input capacitance requiring feed-forward compensation (CZ = 11 × RF/RG pF) when RG || RF > 5kΩ. The device is specified for –40°C to +85°C operation and features 70dB minimum CMRR and 75dB minimum PSRR over temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-noise, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4252EBL+T | Same 8-bump UCSP package, identical 3MHz GBW and 400µA IQ, but lacks shutdown pins | No per-channel power gating - unsuitable for duty-cycled sensor nodes requiring µA-level sleep current | Select MAX4252EBL+T only when shutdown functionality is unnecessary and board space permits same-footprint substitution |
| OPA2333AIDRGT | Zero-drift architecture, 0.02µV/°C offset drift vs. 0.3µV/°C, but higher 17µA IQ and no shutdown mode | Better DC stability for long-duration measurements; higher power prohibits use in battery-critical designs | Choose OPA2333AIDRGT for precision DC-coupled systems where offset drift dominates error budget and power is secondary |
Compared with MAX4252EBL+T and OPA2333AIDRGT, the MAX4253EBC+T uniquely balances ultra-low power (0.5µA shutdown), dual independent shutdown, and 7.9nV/√Hz noise in a 2.1mm × 1.6mm UCSP - making it optimal for space- and energy-constrained dual-channel signal chains where both AC fidelity and standby efficiency are mandatory.

FAQ
What is the operating temperature range for the MAX4253EBC+T?
The MAX4253EBC+T is specified for operation from –40°C to +85°C. This industrial temperature range is validated across all electrical parameters including input offset voltage (±0.75mV max), CMRR (70dB min), and supply current (400µA typ per amplifier). The device uses the same die as other members of the MAX4249–MAX4257 family and shares qualification testing per AEC-Q100 stress protocols for reliability assurance.
Does the MAX4253EBC+T support true rail-to-rail input operation?
No, the MAX4253EBC+T does not support rail-to-rail input. Its input common-mode voltage range is specified from –0.2V to VDD – 1.1V, meaning it can sense signals down to 200mV below ground (enabling ground-referenced sensor use) but cannot accept inputs within 1.1V of VDD. This limitation is inherent to its input stage topology and is explicitly documented in the Absolute Maximum Ratings and Electrical Characteristics tables for the MAX4253EBC+T.
How do I configure feed-forward compensation for the MAX4253EBC+T?
For the MAX4253EBC+T, add a feed-forward capacitor CZ between the inverting input (e.g., INA− or INB−) and the corresponding output (OUTA or OUTB). Use CZ = 11 × (RF / RG) pF, where RF and RG are the feedback and gain-setting resistors. Compensation is required when the parallel resistance RG || RF exceeds 5kΩ. For example, with RG = 1kΩ and RF = 10kΩ (AV = 11V/V), CZ = 110pF. This cancels the pole introduced by the 11pF input capacitance and maintains phase margin above 68°.
Can the MAX4253EBC+T drive a 1000pF capacitive load?
The MAX4253EBC+T is guaranteed stable up to 400pF without external compensation. To drive a 1000pF load, an isolation resistor (RISO) must be placed in series with the output. Per Analog Devices' Figure 6, RISO = 150Ω limits peaking to <2dB. This resistor decouples the op amp's output stage from the capacitive load, restoring phase margin. Without RISO, the device exhibits significant overshoot and potential oscillation at unity gain when driving >400pF.
What is the maximum output current capability of the MAX4253EBC+T?
The MAX4253EBC+T delivers ±5mA continuous output current per amplifier, verified by the 68mA short-circuit current specification and output voltage swing tests into 1kΩ loads. At VDD = 5V, it sustains rail-to-rail swing (within 77mV of rails) into 1kΩ, confirming ≥4.92V output compliance. This drive strength supports direct interfacing with medium-impedance ADC inputs, LED drivers, and analog multiplexers without external buffers.
