Product details
Overview
MAX6008AESA+ from Maxim Integrated is a precision 2.5V 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 2Ω reverse dynamic impedance. It serves as a low-power, high-accuracy replacement for LT1004 and LM285 in battery-powered sensor signal conditioning.
For engineers reviewing the MAX6008AESA+ datasheet, MAX6008AESA+ pinout, MAX6008AESA+ application, or MAX6008AESA+ equivalent, key selection criteria include ultra-low quiescent current, tight initial tolerance, low thermal drift, and compatibility with space-constrained PCB layouts requiring 8-pin SO footprint.
Technical Context
The MAX6008AESA+ implements a laser-trimmed series bandgap core with on-chip thin-film resistors to achieve 0.2% output voltage accuracy at +25°C. Its two-terminal architecture requires external biasing via RBIAS to set operating current between 0.5µA and 2mA.
It delivers stable 2.500V ±0.005V (min/max) reverse breakdown voltage at 1.2µA test current, with low-frequency noise of 60µVP-P (0.1Hz–10Hz) and thermal hysteresis limited to 200ppm - critical for precision ADC reference and portable meter calibration circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±0.005V at 1.2µA - ensures 0.2% absolute accuracy for 12-bit+ ADC reference without trimming. |
| Initial Accuracy | ±0.2% - guarantees full-scale error ≤2.5mV at room temperature, enabling single-point calibration in field instruments. |
| Temp Coefficient | ≤30ppm/°C - limits worst-case drift to ±2.25mV across -40°C to +85°C, supporting industrial-grade stability. |
| Operating Current | 0.5µA to 2mA - supports operation down to sub-µA bias, ideal for coin-cell-powered IoT sensors. |
| Dynamic Impedance | 2Ω (1.2µA–2mA) - minimizes load-induced voltage shift during transient current demands in precision regulators. |
| Low-Freq Noise | 60µVP-P (0.1Hz–10Hz) - reduces quantization uncertainty in high-resolution data acquisition systems. |
| Long-Term Drift | 150ppm/1000h - predicts <0.38mV output change over 1 year, suitable for maintenance-free field deployments. |
Pinout & Package
MAX6008AESA+ uses an 8-pin SO package (package code S8+2, outline 21-0041), with thermal resistance θJA = 136°C/W on multilayer board. Pin 1 is OUT, Pin 4 is GND; Pins 1, 2, 3, 5, 7 are NC except Pin 6 and Pin 8 which are internally connected to OUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6, 8 | OUT | Reference output node - must be biased above VR via RBIAS and bypassed with ≥0.01µF capacitor to GND. |
| 4 | GND | Ground reference - provides return path for bias and load currents; shared with system ground plane. |
| 2, 3, 5, 7 | N.C. | No internal connection - must remain unconnected or grounded per layout best practice to avoid parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low operating current | Guaranteed <1µA minimum - enables >10-year battery life in wireless sensor nodes with µA-level sleep current budgets. |
| Laser-trimmed bandgap core | 0.2% initial accuracy at +25°C - eliminates need for post-assembly calibration in portable medical devices. |
| Low thermal hysteresis | 200ppm max - ensures repeatable voltage after thermal cycling, critical for lab-grade handheld meters. |
| Wide operating current range | 0.5µA to 2mA - accommodates variable load conditions without sacrificing accuracy or stability. |
| Low-frequency noise performance | 60µVP-P (0.1Hz–10Hz) - preserves SNR in DC-coupled instrumentation amplifiers and weigh scale front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar shunt voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM4040C25IDBZR | 2.5V, 0.5% initial accuracy, 100ppm/°C TC, SOT23-3 package, 60µA min operating current | Higher power consumption and lower accuracy limit use in ultra-low-power or high-precision metrology | Select when cost sensitivity outweighs accuracy/power requirements and SOT23-3 footprint is mandatory |
| LT1004CZ-2.5 | 2.5V, 1% initial accuracy, 100ppm/°C TC, TO-92 and SO-8 packages, 10µA min operating current | Lower accuracy and higher drift reduce suitability for 12-bit+ systems and wide-temperature deployments | Select only for legacy redesigns where pin compatibility with older LT1004-based boards is required |
Compared with LM4040C25IDBZR and LT1004CZ-2.5, the MAX6008AESA+ delivers 2.5× tighter initial accuracy, 3.3× lower temperature coefficient, and 60× lower minimum operating current - making it the preferred choice for next-generation portable instrumentation demanding both precision and energy efficiency.

FAQ
What is the guaranteed output voltage tolerance of MAX6008AESA+ at +25°C?
The MAX6008AESA+ guarantees a reverse breakdown voltage of 2.4950V to 2.5050V at +25°C and 1.2µA test current, corresponding to ±0.2% initial accuracy. This specification is 100% production tested and applies to every unit shipped, ensuring consistent performance in precision voltage reference applications without post-manufacturing calibration.
Can MAX6008AESA+ operate reliably below 1µA bias current?
Yes - the MAX6008AESA+ guarantees stable operation down to 0.5µA minimum operating current (IRMIN), with output voltage change limited to <0.2% relative to its value at 1.2µA. This enables deployment in ultra-low-power systems such as energy-harvesting sensors and always-on environmental monitors where average current must remain sub-microamp.
What is the recommended output capacitance for MAX6008AESA+?
The MAX6008AESA+ requires a minimum 0.01µF capacitor from OUT to GND to ensure stability and suppress noise. Larger values (e.g., 0.1µF) improve transient response during step-load changes but do not degrade performance. Ceramic X7R or C0G types are preferred for low ESR and stable capacitance across temperature.
Does MAX6008AESA+ have automotive qualification?
No - the MAX6008AESA+ is rated for the extended industrial temperature range (-40°C to +85°C) but does not carry AEC-Q100 qualification. For automotive applications, the pin-compatible MAX6008AEUR/V+T variant (SOT23-3 package) is AEC-Q100 qualified; the MAX6008AESA+ is intended for industrial, medical, and portable commercial equipment.
How does the 8-pin SO package of MAX6008AESA+ differ electrically from the SOT23 version?
The MAX6008AESA+ (8-pin SO) and MAX6008AEUR+T (3-pin SOT23) share identical electrical specifications - same 2.5V output, 0.2% accuracy, 30ppm/°C TC, and <1µA operating current. The SO package offers lower thermal resistance (θJA = 136°C/W vs. 274°C/W for SOT23), improved power dissipation margin (588mW vs. 292mW at +70°C), and enhanced layout flexibility for high-reliability PCBs.
