Product details

Overview

AP393AM8G-13 from Diodes Incorporated is a dual precision voltage comparator IC featuring ±4 mV input offset voltage, 0.4 mA supply current independent of supply voltage, and rail-to-rail input common-mode range including ground-enabling single-supply sensing near 0 V in battery-powered limit detection circuits.

For engineers reviewing the AP393AM8G-13 datasheet, AP393AM8G-13 pinout, AP393AM8G-13 application, or AP393AM8G-13 equivalent, key selection criteria include low-power operation under 2–36 V single supply, TTL/CMOS-compatible open-collector outputs, and guaranteed offset performance across 0°C to +70°C ambient.

Technical Context

The AP393A employs PNP-input transistor pairs with matched emitter-base junctions to achieve low input bias current (150 nA typ.) and low offset current (±70 nA), while its uncommitted NPN output stage supports wired-OR logic and flexible pull-up voltage selection up to 36 V. Input common-mode range extends from ground to V₊ − 1.5 V at 25°C.

It operates with dual supplies (±1.0 V to ±18 V) or single supply (2.0 V to 36 V), and its differential input voltage rating reaches ±36 V-exceeding supply rails-enabling robust overvoltage-tolerant signal conditioning without external clamping in many configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.0 V to 36 V single supply; ±1.0 V to ±18 V dual supply - supports wide-input industrial and automotive power domains.
Input Offset Voltage	±4 mV max at 25°C - enables accurate threshold detection within ±5 mV windows without trimming.
Supply Current	0.4 mA typ. at 5 V - stable across voltage range, suitable for always-on battery monitoring.
Input Bias Current	150 nA typ. - minimizes loading on high-impedance sensor sources like thermistors or photodiodes.
Output Saturation Voltage	250 mV at 4 mA sink - ensures reliable logic-low assertion into TTL/CMOS inputs with margin.
Input Common-Mode Range	Includes ground (0 V) up to V₊ − 1.5 V - allows direct interface to ground-referenced signals without level-shifting.
Response Time	300 ns typical with 100 mV step & 5 mV overdrive - sufficient for kHz-range pulse generation and zero-crossing detection.

Pinout & Package

AP393AM8G-13 is housed in an MSOP-8L (Mini Small Outline Package, 3 mm × 3 mm, 0.65 mm pitch) with exposed thermal pad per Diodes Inc. AP02001 layout guidelines. RoHS-compliant, green molding compound, lead-free finish.

Pin/Terminal	Circuit Role	Design Meaning
1 - OUTPUT 1	Channel 1 open-collector output	Sinks current to GND; requires external pull-up; supports wired-OR and logic-level translation.
2 - INVERTING INPUT 1	Channel 1 inverting input	Negative input terminal for comparator 1; accepts voltages from GND to V₊ − 1.5 V.
3 - NON-INVERTING INPUT 1	Channel 1 non-inverting input	Positive input terminal for comparator 1; same common-mode range as pin 2.
4 - GND	Analog ground reference	Primary return path for input bias currents and output sink current; must be low-impedance.
5 - NON-INVERTING INPUT 2	Channel 2 non-inverting input	Positive input for comparator 2; electrically isolated from channel 1; identical specs.
6 - INVERTING INPUT 2	Channel 2 inverting input	Negative input for comparator 2; shares same voltage range and bias characteristics as pins 2 & 3.
7 - OUTPUT 2	Channel 2 open-collector output	Independent sink output; can be tied to OUTPUT 1 for OR logic or driven separately.
8 - V+	Positive supply rail	Single-supply connection point; supports up to 36 V; powers both comparators and output stages.

Key Features

Feature	Design Value
Low input offset voltage	±4 mV max ensures sub-10 mV threshold accuracy without calibration in sensor interface circuits.
Ground-sensing input range	Common-mode range includes 0 V on single supply - eliminates need for negative rail in level-shifted analog monitoring.
Supply-current independence	0.4 mA consumption constant from 2 V to 36 V - simplifies power budgeting across variable-battery or wide-input systems.
Logic-family compatibility	Open-collector outputs interface directly with TTL, CMOS, ECL, DTL, and MOS - no level translators required.
High differential input voltage tolerance	±36 V rating allows input signals exceeding V+ - reduces need for external protection in noisy or high-voltage environments.

Applications

Battery Voltage Monitor

Zero-Crossing Detector

Use Scenario: Monitoring Li-ion cell voltage during charging/discharging to trigger cutoff at 2.8 V and 4.2 V thresholds.

IC Role / Device Role / Timing Role: Dual comparator configured as window detector with hysteresis; one channel monitors low threshold, the other high threshold.

Use Value: 0.4 mA quiescent current extends battery life; ground-referenced inputs eliminate need for resistive divider offset.

Use Scenario: Converting AC line voltage (120 V_RMS) to clean digital zero-cross pulses for phase-controlled dimmers.

IC Role / Device Role / Timing Role: Single comparator with resistive attenuator and RC filtering; compares scaled AC waveform against 0 V reference.

Use Value: Input common-mode range including ground enables direct 0 V reference; 300 ns response ensures <1 µs timing jitter at 60 Hz.

Pulse Width Modulator (PWM) Reference

Industrial Limit Switch Interface

Use Scenario: Generating fixed-frequency PWM by comparing sawtooth ramp against adjustable DC reference in motor control feedback loops.

IC Role / Device Role / Timing Role: One comparator acts as threshold detector; second channel unused or configured for fault flagging.

Use Value: Low 4 mV offset minimizes duty-cycle error; rail-to-rail input accommodates full ramp swing without clipping.

Use Scenario: Interfacing mechanical limit switches (dry contact) to PLC input modules requiring 5–24 V logic levels.

IC Role / Device Role / Timing Role: Comparator used as voltage-level translator and noise filter; hysteresis suppresses contact bounce.

Use Value: Open-collector output pulls down to GND while accepting 24 V pull-up - matches standard industrial I/O voltage ranges.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual open-collector comparator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LM393DR	Higher input offset voltage (±7 mV max), higher supply current (0.8 mA typ.), same MSOP-8 footprint.	Less precise thresholding; less suitable for low-voltage battery cutoff where 4 mV offset matters.	Select LM393DR only when cost is primary constraint and ±7 mV offset is acceptable.
TLV3702IDR	Rail-to-rail input/output, lower supply current (80 µA), but requires ≥2.7 V supply and lacks ±36 V differential input rating.	Not usable in 2.0–2.6 V or >36 V differential signal environments; better for ultra-low-power sub-3 V systems.	Choose TLV3702IDR only for battery-powered sub-3 V designs where rail-to-rail output swing is critical.

Compared with LM393DR and TLV3702IDR, AP393AM8G-13 uniquely combines 2.0 V minimum supply, ±36 V differential input tolerance, and ±4 mV offset - making it optimal for wide-input industrial sensing where precision and ruggedness coexist.

FAQ

Can AP393AM8G-13 operate from a 2.0 V single supply?

Yes. The AP393AM8G-13 is fully specified from 2.0 V to 36 V single supply, with guaranteed performance including 0.4 mA supply current, ±4 mV offset, and functional output saturation at 2.0 V. Its PNP input stage enables operation down to this minimum voltage without degradation in input common-mode range or response time.

Does AP393AM8G-13 require external pull-up resistors on its outputs?

Yes. Both outputs are open-collector NPN transistors referenced to GND. An external pull-up resistor to any voltage ≤36 V (including V+, 5 V, or 3.3 V) is mandatory to establish logic-high states. Typical values range from 2.2 kΩ to 10 kΩ depending on speed and load requirements.

What is the maximum differential input voltage the AP393AM8G-13 can withstand?

The absolute maximum differential input voltage is ±40 V, and the recommended operating differential input voltage is ±36 V - exceeding the supply rails. This allows direct connection of signals such as unattenuated AC line derivatives or high-side current sense voltages without clamping diodes in many cases.

How does the input common-mode range behave when using a single 5 V supply?

With V+ = 5 V, the input common-mode range spans 0 V to 3.5 V (V+ − 1.5 V) at 25°C. This includes ground, enabling direct comparison of signals referenced to system GND - e.g., thermistor dividers or op-amp outputs - without level-shifting circuitry.
