Product details
Overview
MAX9064EBS+TG45 from Analog Devices is a nanoPower single comparator with integrated 0.2V reference, push-pull output, and 4-bump UCSP (1mm × 1mm) package. It operates from 1.0V to 5.5V supply, draws ≤700nA quiescent current, and delivers 15µs propagation delay over –40°C to +85°C - ideal for low-voltage battery monitoring in portable medical devices.
For engineers reviewing the MAX9064EBS+TG45 datasheet, MAX9064EBS+TG45 pinout, MAX9064EBS+TG45 application, or MAX9064EBS+TG45 equivalent, key selection criteria include its internal 0.2V reference accuracy (±12mV hysteresis), push-pull output eliminating external pull-up, ultra-low supply current scalability across VCC (1.0–5.5V), and guaranteed operation down to 1V supply - critical for single-cell AA/AAA-powered systems.
Technical Context
The MAX9064EBS+TG45 implements a noninverting-input comparator architecture with an internal temperature-compensated 0.2V reference and push-pull output stage capable of sourcing/sinking current without external components. Its input voltage range extends from –0.3V to +5.5V independent of VCC, enabling robust interfacing with signals exceeding supply rails.
This device uses BiCMOS process technology to achieve high input impedance even when powered down (VCC = 0V), supports RF-immune operation via on-chip filtering, and maintains stable trip-point performance across –40°C to +85°C with reference tempco of 6µV/°C and PSRR of 40–53dB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.0V to 5.5V - enables direct use with single alkaline or Li-ion cells without regulation. |
| Quiescent Supply Current | ≤700nA (max) - extends battery life in always-on sensing nodes beyond 10 years on coin cell. |
| Reference Voltage | 0.2V ±12mV hysteresis - provides precise low-threshold detection for battery end-of-life or sensor zero-crossing. |
| Propagation Delay | 15µs (typ) at ±100mV overdrive - balances speed and power for wake-up event detection in ultra-low-power systems. |
| Input Voltage Range | –0.3V to +5.5V - allows direct connection to unregulated sources or signals exceeding VCC without clamping diodes. |
| Output Type | Push-pull - eliminates need for external pull-up resistor, reducing BOM count and PCB area in space-constrained designs. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and portable medical environments without derating. |
Pinout & Package
MAX9064EBS+TG45 is housed in a 4-bump UCSP package (1.0mm × 1.0mm × 0.6mm), RoHS-compliant with protective die coating (G45). Bump pitch is 0.5mm; land pattern follows Maxim/Analog Devices outline 21-0789 (B4+1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | OUT | Push-pull output - actively drives high/low; compatible with 1.0–5.5V logic interfaces without external components. |
| A2 | IN | Noninverting input - accepts signals from –0.3V to +5.5V; high-impedance (>1GΩ) even during power-down. |
| B1 | VCC | Power-supply input - bypass to GND with 0.1µF capacitor; powers internal reference and output stage. |
| B2 | GND | Ground reference - common return for VCC, IN, and OUT; must be low-impedance for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Internal 0.2V Reference | Stable, temperature-compensated threshold eliminates external reference IC or resistor divider, saving board space and calibration effort. |
| Push-Pull Output | Reduces system-level component count by removing external pull-up resistor - critical for miniaturized wearable and implantable devices. |
| Ultra-Low 700nA Max Supply Current | Enables multi-year operation from CR2032 coin cells in always-on battery voltage monitors and sensor wake-up circuits. |
| Input Overvoltage Tolerance | Supports –0.3V to +5.5V input range regardless of VCC - simplifies interface to unregulated sensors, legacy analog outputs, or hot-swap lines. |
| RF Immunity via On-Chip Filtering | Minimizes false triggering from EMI in noisy portable environments (e.g., near cellular transceivers or switching regulators). |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3691IDCKR | Open-drain output; requires external pull-up; 350nA max ICC; 1.8V–5.5V VCC only. | Lacks push-pull drive; unsuitable for direct GPIO wake-up without added resistor; narrower supply range. | Select when open-drain flexibility is needed for level-shifting, but accept higher system-level component count. |
| MAX40005XK+T | Push-pull output; 900nA max ICC; 1.6V–5.5V VCC; no internal reference - requires external 0.2V source. | Higher supply current; needs external reference circuitry; not drop-in for reference-integrated designs. | Choose only if tighter offset voltage (<0.5mV) is required and external reference is already present in system. |
Compared with TLV3691IDCKR and MAX40005XK+T, MAX9064EBS+TG45 uniquely combines push-pull output, internal 0.2V reference, 1V minimum supply, and ≤700nA current - delivering lowest total solution size and power for single-cell battery threshold detection.

FAQ
What is the function of the G45 suffix in MAX9064EBS+TG45?
The G45 suffix denotes protective die coating applied to the MAX9064EBS+TG45 die - enhancing moisture resistance and mechanical robustness for reliability in humid or mechanically stressed portable applications. This coating is part of the UCSP package construction and does not affect electrical specifications or pinout of the MAX9064EBS+TG45.
Does MAX9064EBS+TG45 require an external pull-up resistor?
No, MAX9064EBS+TG45 features a push-pull output stage that actively drives both high and low states, eliminating the need for an external pull-up resistor. This distinguishes it from MAX9060–MAX9063 variants and reduces component count and PCB area in designs using the MAX9064EBS+TG45.
What is the absolute maximum input voltage rating for MAX9064EBS+TG45?
The absolute maximum input voltage for MAX9064EBS+TG45 is –0.3V to +6V relative to GND, as specified in the Absolute Maximum Ratings table. This overvoltage tolerance applies regardless of VCC level and enables safe interfacing with signals exceeding the supply rail - a key feature confirmed for the MAX9064EBS+TG45 in its datasheet.
Can MAX9064EBS+TG45 operate from a single 1.0V supply?
Yes, MAX9064EBS+TG45 is fully specified to operate from VCC = 1.0V to 5.5V, with all key parameters (including 0.2V reference accuracy, 700nA max ICC, and 15µs propagation delay) guaranteed across this range. This makes the MAX9064EBS+TG45 suitable for direct integration with ultra-low-voltage microcontrollers and single-cell battery systems.
How does the internal 0.2V reference of MAX9064EBS+TG45 perform over temperature?
The internal 0.2V reference of MAX9064EBS+TG45 exhibits a tempco of 6µV/°C and remains within 185mV to 215mV over –40°C to +85°C. This stability is confirmed in the MAX9064-specific Electrical Characteristics table and Typical Operating Characteristics (Figure MAX9060 toc11), ensuring reliable thresholding across environmental conditions for the MAX9064EBS+TG45.
