Analog Devices Inc./Maxim Integrated MAX9095AUD+T

Overview

MAX9095AUD+T from Maxim Integrated is a quad, low-voltage, open-drain comparator with internal 2mV hysteresis, operating from +1.8V to +5.5V supply, featuring 100ns propagation delay, 120mV output saturation voltage at 4mA sink, and -40°C to +125°C automotive temperature range-used in battery-powered portable devices for precise voltage monitoring and threshold detection.

For engineers reviewing the MAX9095AUD+T datasheet, MAX9095AUD+T pinout, MAX9095AUD+T application, or MAX9095AUD+T equivalent, key selection criteria include guaranteed hysteresis, rail-to-rail input common-mode range including ground, low 360µA total supply current (all four comparators), open-drain output compatibility with mixed-voltage logic, and TSSOP-14 packaging for high-density PCB layouts.

Technical Context

The MAX9095AUD+T implements a BiCMOS quad comparator architecture with independent input stages per channel, each supporting input common-mode voltage from -0.1V to VDD – 0.8V and no phase reversal under overdrive. Its internal hysteresis is fixed at 2mV and applies uniformly across all four comparators.

Each comparator features open-drain output capable of sinking up to 35mA, with output leakage below 2µA over full temperature range. Propagation delay is specified at 100ns (tPLH) and 70ns (tPHL) under 100mV input overdrive at VDD = 5V, with performance maintained down to 1.8V supply.

Key Specifications

FAQ

What is the maximum operating temperature range for the MAX9095AUD+T?

The MAX9095AUD+T is rated for continuous operation from -40°C to +125°C, meeting automotive-grade thermal requirements. This specification is guaranteed across all electrical parameters in the datasheet, including input offset voltage, propagation delay, and supply current, making the MAX9095AUD+T suitable for under-hood or industrial enclosure deployments where ambient temperatures exceed 85°C.

Does the MAX9095AUD+T require external hysteresis components?

No, the MAX9095AUD+T integrates 2mV of internal hysteresis across all four comparators, eliminating the need for external positive-feedback resistors. This hysteresis is factory-trimmed and remains stable over temperature (-40°C to +125°C) and supply voltage (1.8V–5.5V), enabling reliable noise immunity in applications such as battery voltage monitoring or motor control feedback loops without additional board area or BOM cost.

What is the output configuration of the MAX9095AUD+T and how should it be interfaced?

The MAX9095AUD+T features four independent open-drain outputs (OUTA–OUTD), each requiring an external pull-up resistor to a logic-compatible voltage (e.g., 1.8V, 3.3V, or 5V). This configuration allows level translation, wired-OR logic, and shared interrupt lines. The output can sink up to 35mA while maintaining ≤120mV saturation voltage at 4mA, ensuring compatibility with standard CMOS and TTL inputs when properly terminated.

Can the MAX9095AUD+T operate from a 1.8V supply, and what performance changes occur?

Yes, the MAX9095AUD+T is fully specified for operation down to +1.8V supply. At 1.8V, propagation delay increases slightly (tPLH ≈ 120ns, tPHL ≈ 70ns), supply current drops to ~210µA (typ), and output sink capability reduces to 6.4mA (min). Input common-mode range remains functional from -0.1V to +1.0V, preserving ground-referenced sensing capability-making the MAX9095AUD+T ideal for modern ultra-low-voltage microcontroller subsystems.

Is the MAX9095AUD+T pin-compatible with other devices in the MAX909x family?

Yes, the MAX9095AUD+T shares identical pinout and footprint with MAX9094AUD+, MAX9092AKA+, and MAX9093AKA+ in their respective packages. All TSSOP-14 variants (MAX9094AUD+, MAX9095AUD+) use the same 14-pin mapping; SOT23/μMAX variants differ only in channel count (dual vs. quad) and pin count (8-pin), so direct substitution requires board-level verification. The MAX9095AUD+T is functionally and physically compatible with MAX9094AUD+ in TSSOP-14 layouts.
