Product details
Overview
MAX6006AESA+T from Maxim Integrated is a precision 1.25V two-terminal shunt voltage reference in an 8-pin SO package, featuring 0.2% initial accuracy, 30ppm/°C temperature coefficient over -40°C to +85°C, <1µA guaranteed operating current, and low-frequency noise of 30µVP-P (0.1Hz–10Hz). It serves as a stable voltage reference for high-resolution ADCs, battery-powered meters, and low-power precision regulators.
For engineers reviewing the MAX6006AESA+T datasheet, MAX6006AESA+T pinout, MAX6006AESA+T application, or MAX6006AESA+T equivalent, key selection criteria include ultra-low quiescent current, tight initial tolerance, thermal stability across industrial temperature range, and compatibility with standard 8-pin SO footprint for drop-in replacement of legacy references like LT1004 in precision analog signal chains.
Technical Context
The MAX6006AESA+T implements a laser-trimmed series bandgap core with on-chip thin-film resistors, enabling factory-set 1.25V output with 0.2% accuracy at +25°C. Its two-terminal architecture requires external biasing via RBIAS to maintain reverse current between 0.5µA and 2mA for stable regulation.
It operates as a shunt device-sinking current to ground to hold VOUT constant-making it suitable for applications where supply headroom is limited or where load current varies significantly. The 8-pin SO package provides improved thermal performance (θJA = 136°C/W) versus SOT23 variants, supporting higher power dissipation up to 588.2mW at +70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 1.25V ±0.2% at +25°C - enables precise scaling in 12-bit+ ADC systems without calibration. |
| Initial Accuracy | ±0.2% - reduces system-level gain error in portable instrumentation and sensor front-ends. |
| Temp Coefficient | ≤30ppm/°C (-40°C to +85°C) - ensures ≤±0.375mV drift over full industrial range. |
| Min Operating Current | 0.5µA - supports operation from microampere-level energy harvesters or coin-cell sources. |
| Low-Freq Noise | 30µVP-P (0.1Hz–10Hz) - minimizes quantization uncertainty in high-resolution DC measurements. |
| Dynamic Impedance | 1.5Ω (1.2µA–2mA) - maintains output stability under dynamic load transients in closed-loop regulators. |
| Long-Term Drift | 150ppm (1000h) - ensures reference stability over multi-year deployment in embedded monitoring systems. |
Pinout & Package
MAX6006AESA+T uses an 8-pin SO (Small Outline) package (package code S8+2, outline 21-0041), with thermal resistance θJA = 136°C/W on multilayer board. Pin 1 is OUT, Pin 2 is GND, Pins 3, 5, 7 are N.C., Pin 4 is GND (dual ground), Pin 6 is OUT (redundant output), Pin 8 is N.C. Internally connected test point (IC) is not present in SO variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6 | OUT | Dual-output terminals for 1.25V reference; connect together externally; bypass to GND with ≥0.01µF capacitor. |
| 2, 4 | GND | Two dedicated ground pins reduce ground path impedance and improve PSRR in noisy environments. |
| 3, 5, 7, 8 | N.C. | No internal connection; must remain unconnected per datasheet to avoid parasitic coupling or latch-up. |

FAQ
What is the output voltage tolerance of MAX6006AESA+T over temperature?
The MAX6006AESA+T guarantees ±0.2% initial accuracy at +25°C and a maximum temperature coefficient of 30ppm/°C across -40°C to +85°C. This results in total output variation of ≤±0.375mV (±0.03%) over the full industrial temperature range, confirmed by box-method testing per datasheet Note 3.
Can MAX6006AESA+T operate with less than 1µA supply current?
Yes, MAX6006AESA+T is guaranteed to regulate stably with as little as 0.5µA reverse current (IRMIN). Its ultra-low operating current specification (<1µA) is fully characterized and production-tested, making it suitable for energy-harvesting and coin-cell-powered applications where current budgets are sub-microampere.
What is the purpose of the dual OUT pins (Pins 1 and 6) on MAX6006AESA+T?
The dual OUT pins (Pins 1 and 6) on MAX6006AESA+T provide redundant 1.25V reference outputs to reduce trace inductance and ground loop effects in high-precision layouts. They must be connected together externally and bypassed to GND with a single ≥0.01µF capacitor-this configuration improves PSRR and stabilizes regulation under fast load transients.
Is MAX6006AESA+T pin-compatible with LT1004 in the 8-pin SO package?
MAX6006AESA+T is offered as a plug-in upgrade for LT1004 in 8-pin SO packaging, but pin functions differ: LT1004 uses Pin 1 as ADJ and Pin 8 as VOUT, whereas MAX6006AESA+T uses Pins 1 and 6 as OUT and Pins 2/4 as GND. Direct replacement requires PCB layout revision-no pin-to-pin compatibility exists despite shared package outline.
Does MAX6006AESA+T require an external capacitor, and what value is recommended?
Yes, MAX6006AESA+T requires an output bypass capacitor of ≥0.01µF connected between OUT and GND to ensure stability and low-noise operation. Ceramic capacitors are recommended; larger values (e.g., 0.1µF) further improve transient response in applications with step-load changes, as confirmed in the Typical Operating Characteristics section of the datasheet.
