Product details
Overview
MAX6198AESA/V+T from Maxim Integrated is a precision, micropower, low-dropout series-mode bandgap voltage reference delivering 4.096V output with ±2mV initial accuracy, 5ppm/°C max temperature coefficient, and 35µA max quiescent current - designed for high-accuracy ADC/DAC biasing in battery-powered industrial instrumentation.
For engineers reviewing the MAX6198AESA/V+T datasheet, MAX6198AESA/V+T pinout, MAX6198AESA/V+T application, or MAX6198AESA/V+T equivalent, this page provides verified electrical specifications, SO-8 package layout, load-regulation behavior at ±500µA, dropout performance at 100mV, and validated alternatives for precision 4.096V reference designs.
Technical Context
The MAX6198AESA/V+T uses a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve <5ppm/°C temperature coefficient and ±2mV initial accuracy over -40°C to +85°C. It operates as a series-mode reference capable of sourcing and sinking up to 500µA while maintaining regulation.
Internally compensated for stability with capacitive loads up to 2.2nF, it exhibits 160µs typical turn-on settling time to 0.1% and 77dB ripple rejection at 120Hz - enabling direct integration into high-resolution data acquisition systems without external compensation.

Pinout & Package
MAX6198AESA/V+T is housed in an 8-pin SO (Small Outline) package, RoHS-compliant and automotive-qualified (-40°C to +85°C). Pin 1 is OUT; pins 1,3,5,7,8 are No Connect; pin 4 is GND; pin 2 is IN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF5040AIDR | 4.096V, 3ppm/°C max TC, 100µA IQ, SO-8 - higher accuracy but 2.8× higher supply current | Preferred where ultra-low TC dominates over battery life; not suitable for sub-50µA systems | Select REF5040AIDR when TC <3ppm/°C is mandatory and power budget allows ≥100µA |
| ADR444BRZ | 4.096V, 3ppm/°C max TC, 750µA IQ, SO-8 - superior TC/noise but 21× higher quiescent current | Used in lab-grade equipment with unlimited power; incompatible with portable or energy-harvested designs | Choose ADR444BRZ only for bench instruments where lowest possible noise and TC outweigh all power constraints |
Compared with REF5040AIDR and ADR444BRZ, MAX6198AESA/V+T uniquely balances automotive-grade reliability, 35µA ultra-low IQ, and 5ppm/°C TC - making it the optimal choice for battery-operated industrial sensors where both accuracy and multi-year runtime are required.

FAQ
What is the guaranteed initial accuracy of MAX6198AESA/V+T?
The MAX6198AESA/V+T has a guaranteed initial accuracy of ±2mV at +25°C, corresponding to ±488ppm of its 4.096V nominal output. This specification is laser-trimmed and tested per Maxim's production flow, ensuring compliance across the full -40°C to +85°C automotive temperature range without derating.
Does MAX6198AESA/V+T require an output capacitor for stability?
No, MAX6198AESA/V+T is internally compensated and stable with output capacitance ranging from 0 to 2.2nF. An external capacitor is optional and only recommended in applications subject to fast load or supply transients to improve transient response - not for basic stability.
What is the minimum input voltage needed for MAX6198AESA/V+T to regulate at full load?
At 500µA load current, MAX6198AESA/V+T requires a minimum input voltage of VOUT + 100mV = 4.196V to maintain regulation within 0.2% of nominal output. The absolute maximum input is 12.6V, and the device remains functional down to VOUT + 0.2V across its entire operating range.
How does the supply current of MAX6198AESA/V+T vary with input voltage?
MAX6198AESA/V+T draws ≤35µA quiescent current, with variation limited to ≤2µA/V across its input range. For example, supply current changes by no more than 10µA when VIN rises from 4.5V to 9.5V - a key advantage over shunt references whose current scales linearly with input voltage.
Is MAX6198AESA/V+T qualified for automotive applications?
Yes, the "/V" suffix in MAX6198AESA/V+T denotes AEC-Q100 automotive qualification. It is rated for -40°C to +85°C operation, undergoes enhanced reliability testing, and is manufactured in Maxim's automotive-certified processes - making it suitable for engine control, ADAS sensor interfaces, and infotainment power domains.
