Product details
Overview
MAX6160ESA+T from Maxim Integrated is an adjustable, low-dropout, micropower three-terminal voltage reference with 1.23V to (VIN − 0.2V) output range, 200mV dropout, 75μA supply current independent of input voltage, and ±1% initial accuracy - used in precision ADC/DAC biasing, portable instrumentation, and battery-powered sensor signal chains.
For engineers reviewing the MAX6160ESA+T datasheet, MAX6160ESA+T pinout, MAX160ESA+T application, or MAX6160ESA+T equivalent, this page delivers verified pin functions, real-world load regulation (0.35 mV/mA sourcing), thermal hysteresis (80 ppm), ADJ input current (70 nA), and SO-8 package compatibility for production-grade design-in.
Technical Context
The MAX6160ESA+T implements a bandgap-based adjustable reference architecture with internal feedback control via the ADJ pin, requiring external resistor divider (R1/R2) to set VOUT between 1.23V and VIN − 0.2V. Its 200mV dropout enables operation from 2.7V input while delivering stable output up to 12.4V.
It features temperature-compensated ADJ input current (70 nA at +25°C, stable over −40°C to +85°C), 15 ppm/°C typical TCVOUT (guaranteed ≤100 ppm/°C), and stability with capacitive loads up to 10nF - eliminating need for output bypassing in most data-acquisition systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar adjustable voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1790ACS8-2.5#TRPBF | Fixed 2.5V output; 35ppm/°C max tempco; 65μA IQ; SOT-23-5 package | Not adjustable; requires separate part numbers per VOUT; better noise (12µVP-P) but higher tempco | Select when fixed output suffices and board space is constrained (SOT-23-5 vs SO-8) |
| ADR4525BRZ | Fixed 2.5V output; 3ppm/°C max tempco; 950μA IQ; SO-8 package | Higher precision and lower drift, but 12× higher supply current limits battery use | Select for metrology-grade accuracy where power budget allows >900μA continuous draw |
Compared with MAX6160ESA+T, LT1790ACS8-2.5#TRPBF offers smaller footprint and lower noise but lacks adjustability and requires redesign for non-2.5V rails; ADR4525BRZ delivers ultra-low drift yet consumes 12× more current - making MAX6160ESA+T optimal for adjustable, low-power, industrial-grade references.

FAQ
What is the minimum input voltage required for regulation in MAX6160ESA+T?
The MAX6160ESA+T requires VIN ≥ (VOUT + 200mV) to maintain regulation. For example, with a 2.5V output, minimum VIN is 2.7V; with a 12.4V output, minimum VIN is 12.6V. This 200mV dropout is guaranteed across −40°C to +85°C and 0–1mA load.
How do I calculate resistor values to set a specific output voltage on MAX6160ESA+T?
Use R1 = (1.06 × 10⁵) × (VOUT / 1.23) Ω and R2 = R1 / (VOUT / 1.23 − 1). For 2.5V output: R1 ≈ 215kΩ, R2 ≈ 208kΩ (both ±0.1%). The 1.06 × 10⁵ factor compensates for ADJ current drift over temperature, ensuring optimal tempco performance in MAX6160ESA+T.
Does MAX6160ESA+T require an output capacitor for stability?
No. MAX6160ESA+T is internally compensated and stable with capacitive loads from 0nF to 10nF. Adding an output capacitor is unnecessary and may degrade settling time. Only include one if needed for charge reservoir purposes - and ensure total COUT ≤ 10nF for optimal transient response in MAX6160ESA+T.
What is the ADJ pin's voltage threshold and input current in MAX6160ESA+T?
The ADJ pin has a precise 1.23V threshold and draws only 70nA at +25°C (≤120nA over −40°C to +85°C). This ultra-low input current enables high-value resistor dividers (e.g., 215kΩ/208kΩ), minimizing power loss and self-heating errors in MAX6160ESA+T designs.
Is MAX6160ESA+T compatible with the 8-pin SO package footprint of other MAX61xx devices?
Yes. MAX6160ESA+T uses the same 8-pin SO (SOIC-8) package as MAX6125ESA, MAX6141ESA, MAX6145ESA, and MAX6150ESA - including identical pin 1 location, body dimensions (4.9mm × 6.0mm), and lead pitch (1.27mm). This allows direct PCB footprint reuse across the MAX61xx family.
