Analog Devices Inc./Maxim Integrated MAX9060EBS+TG45

Overview

The MAX9060EBS+TG45 from Analog Devices is a nanoPower single comparator with open-drain output, noninverting input, and external reference input (0.9V–5.5V), consuming only 100nA max supply current, operating from –40°C to +85°C, and housed in a 1mm × 1mm × 0.6mm 4-bump UCSP package-ideal for ultra-compact battery-powered sensor monitoring circuits in portable medical devices.

For engineers reviewing the MAX9060EBS+TG45 datasheet, MAX9060EBS+TG45 pinout, MAX9060EBS+TG45 application, or MAX9060EBS+TG45 equivalent, key selection considerations include its 100nA max quiescent current, –0.3V to +5.5V input voltage range independent of supply, open-drain output requiring external pull-up, 15µs propagation delay, and compatibility with low-voltage microcontrollers down to 0.9V reference rails.

Technical Context

The MAX9060EBS+TG45 implements a BiCMOS input stage enabling rail-to-rail input operation beyond VREF (up to –0.3V to +5.5V) while maintaining high input impedance even when powered down (VREF = 0V). Its architecture eliminates traditional ESD diode clamps between input and supply, supporting flexible power sequencing in multi-rail systems.

It features internal hysteresis (±12mV typical) for noise immunity and integrates on-chip RF filtering. The open-drain output supports level-shifting across different logic domains via an external pull-up resistor, and the device draws supply current solely from the VREF pin-not VCC-making it suitable for applications where VREF is derived from a precision DAC or low-noise LDO.

FAQ

What is the maximum supply current specification for MAX9060EBS+TG45?

The MAX9060EBS+TG45 has a maximum supply current of 100nA across the full –40°C to +85°C temperature range. This value is measured with VREF = 0.9V to 5.5V and represents worst-case quiescent draw, enabling multi-year operation on coin-cell batteries. The MAX9060EBS+TG45 draws this current exclusively from the REF pin, not a separate VCC rail.

Does MAX9060EBS+TG45 support input voltages below ground?

Yes, the MAX9060EBS+TG45 supports input voltages as low as –0.3V relative to GND, independent of the REF voltage. This negative input capability allows direct interfacing with bipolar sensors or AC-coupled signals without level-shifting circuitry. The input stage maintains high impedance even when REF = 0V, preventing unwanted loading during system power-down.

What package type and dimensions does MAX9060EBS+TG45 use?

The MAX9060EBS+TG45 uses a 4-bump UCSP (Ultra Compact Silicon Package) with a 1.0mm × 1.0mm footprint and 0.6mm height. The bumps are located on the bottom surface, and the top-side marking is "AFX". The G45 suffix indicates protective die coating for improved moisture resistance-critical for portable consumer and medical applications exposed to humidity.

Can MAX9060EBS+TG45 operate with a 1.0V reference voltage?

Yes, the MAX9060EBS+TG45 is fully specified to operate with VREF as low as 0.9V, including 1.0V. At 1.0V REF, the device maintains 100nA max supply current, 15µs propagation delay, and functional input range from –0.3V to +5.5V. This enables direct use with low-voltage MCUs and energy-harvesting systems where supply rails dip below 1.2V.

What is the function of the B1 terminal on MAX9060EBS+TG45?

The B1 terminal on MAX9060EBS+TG45 is the REF pin, which serves dual functions: it provides the internal reference voltage for comparison and supplies all operating current to the device. It must be bypassed to GND with a 0.1µF capacitor placed as close as possible to the pin. Unlike conventional comparators, MAX9060EBS+TG45 has no separate VCC pin-the REF pin is its sole power source.
