Analog Devices Inc./Maxim Integrated MAX40014ANS09+

Overview

MAX40014ANS09+ from Analog Devices is a nanoPower, noninverting-input comparator with integrated 0.9V precision reference and push-pull output, operating from 1.7V to 5.5V supply, consuming only 500nA typical supply current, and specified over –40°C to +125°C for automotive and portable electronics monitoring applications.

For engineers reviewing the MAX40014ANS09+ datasheet, MAX40014ANS09+ pinout, MAX40014ANS09+ application, or MAX40014ANS09+ equivalent, key selection considerations include its 0.9V factory-trimmed internal reference, 9µs propagation delay (typ), ultra-low quiescent current, WLP package footprint (0.73mm × 0.73mm), and push-pull output eliminating external pull-up requirements.

Technical Context

The MAX40014ANS09+ implements a BiCMOS input stage enabling rail-to-rail input voltage range (0.1V to 5.5V) independent of supply, with high-impedance inputs even at VCC = 0V. Its internal temperature-compensated 0.9V reference provides stable switching thresholds across –40°C to +125°C.

It features 8mV typical internal hysteresis for noise immunity and employs on-chip RF filtering. The push-pull output drives logic directly without external components and supports sourcing up to 1mA and sinking up to 2mA while maintaining VOL ≤ 0.4V and VOH ≥ VCC – 0.4V.

FAQ

What is the internal reference voltage tolerance of MAX40014ANS09+ over temperature?

The MAX40014ANS09+ features a factory-trimmed 0.9V internal reference with ±1.8% tolerance over the full –40°C to +125°C operating range, as specified in the Electrical Characteristics table (page 3, Rev 9). This value is measured at TA = –40°C to +125°C and includes initial trim accuracy and temperature drift. MAX40014ANS09+ maintains this specification without requiring external calibration.

Does MAX40014ANS09+ require an external pull-up resistor on its output?

No, MAX40014ANS09+ does not require an external pull-up resistor because it features a push-pull output stage capable of both sourcing and sinking current. Unlike open-drain comparators (e.g., MAX40012ANS09+), the MAX40014ANS09+ output drives high actively to VCC and low actively to GND, enabling direct interface with standard CMOS inputs without additional components.

Can MAX40014ANS09+ operate with input voltages exceeding its supply voltage?

Yes, MAX40014ANS09+ supports input voltages from 0.1V to 5.5V independent of VCC, allowing VIN to exceed VCC (up to +6V absolute max per Absolute Maximum Ratings). This is enabled by its innovative input-stage architecture without ESD diode clamps to VCC, making it suitable for monitoring battery voltages or other signals outside the system rail.

What is the propagation delay of MAX40014ANS09+ at 1.8V supply?

At VCC = 1.8V and 100mV input overdrive, the MAX40014ANS09+ exhibits a typical propagation delay of 25µs (low-to-high) and 9µs (high-to-low), as confirmed in the Electrical Characteristics table (page 2, Rev 9). These values are guaranteed over –40°C to +125°C and reflect actual timing behavior in real-world low-voltage portable systems.

Is MAX40014ANS09+ pin-compatible with other devices in the MAX400xx family?

MAX40014ANS09+ shares the same 4-bump WLP pinout (A1=OUT, A2=IN, B1=VCC/REF, B2=GND) with all MAX40012–MAX40015 variants in WLP packaging. However, output type (push-pull vs. open-drain) and input polarity (noninverting vs. inverting) differ across part numbers - so while physical pinout is identical, functional replacement requires verification of signal polarity and drive requirements.
