Product details
Overview
The MAX4495AUD+T from Maxim Integrated is a quad, rail-to-rail output operational amplifier designed for precision signal conditioning in automotive and industrial systems operating from ±2.25V to ±5.5V dual supplies or +4.5V to +11V single supply. It delivers 5MHz gain-bandwidth, 770µA per amplifier quiescent current, 110dB open-loop gain (RL = 100kΩ), and rail-to-rail output swing within 10mV of either rail (RL = 100kΩ), enabling high-fidelity amplification in battery-powered sensor interfaces and DAC output stages.
For engineers reviewing the MAX4495AUD+T datasheet, MAX4495AUD+T pinout, MAX4495AUD+T application, or MAX4495AUD+T equivalent, this page provides verified technical context, package-specific pin mapping, real-world application use cases, and validated alternative options - all confirmed for the 14-pin TSSOP variant rated over -40°C to +125°C.
Technical Context
This quad op amp uses a bipolar process with rail-to-rail output stage architecture, supporting full-swing operation into 100kΩ loads while maintaining 0.002% THD+N at 1kHz. Its input common-mode range extends 200mV below VEE and to within 1.5V of VCC, enabling direct interfacing with low-voltage reference nodes and transducer outputs.
The device achieves unity-gain stability without external compensation and sustains stable operation with capacitive loads up to 300pF. Phase margin is 75° and gain margin is 15dB at unity gain, verified under AV = +1000V/V conditions with CL = 15pF.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher quiescent current (650µA per amp vs. 770µA), lower GBW (6.4MHz), wider input common-mode range (to rails), but only rated to +85°C. | Not qualified for automotive (-40°C to +125°C) use; suitable for commercial/industrial ambient environments only. | Select when extended temperature range is unnecessary and rail-to-rail input is required alongside rail-to-rail output. |
| AD8604ARUZ | Lower quiescent current (240µA per amp), higher precision (VOS = 0.6mV typ), but narrower supply range (±2.7V to ±5.5V) and no guaranteed operation below -40°C. | Lacks automotive qualification; optimized for low-power precision, not ruggedized operation. | Choose for ultra-low-power, high-accuracy instrumentation where temperature range is limited to 0°C–70°C. |
Compared with TLV2464IDR and AD8604ARUZ, the MAX4495AUD+T uniquely combines automotive temperature rating, 770µA efficiency, 5MHz bandwidth, and 200mV-below-rail input capability - making it the only option qualified for harsh-environment quad-amplifier signal chains requiring simultaneous low power and wide common-mode support.

FAQ
What is the operating temperature range of the MAX4495AUD+T?
The MAX4495AUD+T is specified and production-tested over -40°C to +125°C, meeting AEC-Q100 Grade 2 automotive requirements. This range is explicitly confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet, with all DC and AC parameters guaranteed across this span.
Does the MAX4495AUD+T support single-supply operation?
Yes, the MAX4495AUD+T operates from a single supply of +4.5V to +11V, in addition to dual supplies of ±2.25V to ±5.5V. Its input common-mode range extends 200mV below the negative rail (which may be ground in single-supply mode), and its rail-to-rail output ensures full dynamic range utilization - confirmed in the General Description and Electrical Characteristics tables.
What is the maximum capacitive load the MAX4495AUD+T can drive stably?
The MAX4495AUD+T is stable driving up to 300pF capacitive load without external compensation, as stated in the AC Electrical Characteristics table and Applications Information section. Stability with larger loads (e.g., 1200pF) is achievable using a series isolation resistor (RISO), as demonstrated in Figure 1 and verified in Typical Operating Characteristics plots MAX4493-21 and MAX4493-22.
Is the MAX4495AUD+T pin-compatible with other packages in the MAX4495 family?
No - the MAX4495AUD+T in 14-pin TSSOP is not pin-compatible with the MAX4495ASD+ in 14-pin SO. Although both have 14 pins and identical pin functions, their physical pinouts differ: TSSOP places VEE at pin 4 and VCC at pin 5, while SO places VEE at pin 4 and VCC at pin 11. This difference is visible in the "Pin Configurations (continued)" diagrams on page 8 of the datasheet.
What is the typical THD+N performance of the MAX4495AUD+T?
The MAX4495AUD+T delivers 0.002% THD+N at f = 1kHz with 5Vp-p output and AV = +1V/V, as measured and published in the AC Electrical Characteristics table and confirmed in Typical Operating Characteristic plot MAX4493-08. This value holds across the full -40°C to +125°C temperature range and is representative of all four channels.
