Product details

Overview

AP358SL-13 from Diodes Incorporated is a low-power dual operational amplifier in SOP-8L package, designed for single-supply operation from 3V to 32V. It delivers 100 dB dc gain, 1 MHz unity-gain bandwidth, 2 mV input offset voltage, and rail-to-rail output swing down to ground-enabling transducer amplification, DC gain blocks, and logic-compatible interface circuits in +5V digital systems.

For engineers reviewing the AP358SL-13 datasheet, AP358SL-13 pinout, AP358SL-13 application, or AP358SL-13 equivalent, key selection criteria include single-supply ground-sensing capability, temperature-compensated unity-gain crossover, low 500 μA supply current, and dual-channel integration in lead-free SOP-8L packaging.

Technical Context

The AP358SL-13 uses a PNP-input stage enabling true differential inputs with common-mode range extending to ground (0 V) and up to V₊ − 1.5 V. Its internal frequency compensation ensures stable unity-gain operation across temperature.

Input bias current (45 nA typ) and offset current (5 nA typ) are temperature-compensated; supply current remains essentially independent of supply voltage (0.5–1.2 mA over 5–30 V), supporting battery-powered and wide-input-voltage industrial designs.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	Single supply: 3 V to 32 V - supports direct +5 V digital system interfacing without ±15 V rails.
DC Voltage Gain	100 dB - enables high-precision DC amplification with <0.1% gain error in closed-loop configurations.
Unity-Gain Bandwidth	1 MHz - sufficient for audio preamps, sensor signal conditioning, and active filter design up to ~100 kHz.
Input Offset Voltage	2 mV max - allows accurate low-level signal amplification (e.g., thermocouple outputs) without external nulling.
Supply Current per Amplifier	500 μA - enables dual-op-amp functionality in power-constrained applications like portable instrumentation.
Output Voltage Swing	0 V to V₊ − 1.5 V - permits ground-referenced output in single-supply configurations, simplifying level-shifting.
Input Common-Mode Range	0 V to V₊ − 1.5 V - supports direct sensing of signals referenced to system ground (e.g., current-sense shunts).

Pinout & Package

SOP-8L surface-mount package (4.9 mm × 3.9 mm × 1.75 mm height), RoHS-compliant, green molding compound, lead-free finish.

Pin/Terminal	Circuit Role	Design Meaning
1	OUTPUT 1	Channel 1 analog output - drives loads up to 40 mA sink / 20 mA source at 25°C.
2	INVERTING INPUT 1	Inverting input of first op amp - accepts differential voltages up to ±32 V without damage.
3	NON-INVERTING INPUT 1	Non-inverting input of first op amp - common-mode range includes ground for true single-supply operation.
4	GND	Analog ground reference - shared return path for both amplifiers and bias network.
5	NON-INVERTING INPUT 2	Non-inverting input of second op amp - electrically isolated but thermally coupled to Channel 1.
6	INVERTING INPUT 2	Inverting input of second op amp - identical electrical specs to Pin 2; supports dual independent gain stages.
7	OUTPUT 2	Channel 2 analog output - fully independent output stage with same drive capability as Pin 1.
8	V+	Positive supply rail - powers both amplifiers; no separate V− required for single-supply use.

Key Features

Feature	Design Value
Ground-sensing input stage	Input common-mode range includes 0 V - eliminates need for input biasing in single-supply sensor interfaces.
Temperature-compensated unity-gain crossover	1 MHz bandwidth stable across 0°C to +70°C - ensures consistent filter cutoff and amplifier response in varying environments.
Low and supply-independent quiescent current	500 μA per amplifier at 5 V - enables dual-op-amp functionality in always-on battery nodes without compromising runtime.
Rail-to-ground output swing	VOL = 20 mV at 10 kΩ load (V+ = 5 V) - supports direct connection to microcontroller ADCs or logic inputs requiring 0 V low state.
High CMRR and PSRR	85 dB CMRR / 100 dB PSRR - rejects noise from shared power rails and common-mode interference in industrial signal chains.

Applications

Use Scenario: Amplifying low-level output from pressure or temperature sensors operating from +5 V supply.

IC Role / Device Role / Timing Role: Dual-channel DC-coupled gain block with ground-referenced input and output.

Use Value: Eliminates dual supplies and external level-shifting; 2 mV offset enables sub-10 mV signal resolution.

Use Scenario: Driving TTL/CMOS inputs or buffering DAC outputs in embedded controllers.

IC Role / Device Role / Timing Role: Voltage follower and level translator between analog subsystems and digital logic.

Use Value: Output swings to 0 V ensures valid logic LOW; 1 MHz bandwidth supports >100 kHz digital control loops.

Battery-Powered Instrumentation

Active Filter Design

Use Scenario: Portable multimeter front-end or handheld data logger analog signal chain.

IC Role / Device Role / Timing Role: Low-power dual op amp for programmable gain and anti-aliasing filtering.

Use Value: 500 μA total supply current extends battery life; SOP-8L footprint minimizes PCB area.

Use Scenario: Second-order bandpass or low-pass active filters in sensor signal processing.

IC Role / Device Role / Timing Role: Dual op amp implementing biquad topology with precise pole placement.

Use Value: 1 MHz GBW and 100 dB gain enable Q > 25 filters at 1 kHz; matched channels improve symmetry.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual low-power op amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LM358DR	Higher 700 μA supply current; 700 kHz GBW; 3 mV V_IO; non-temperature-compensated unity-gain crossover.	Less suitable for precision ground-sensing or battery-critical designs; wider legacy availability.	Select when cost sensitivity outweighs precision and power efficiency requirements.
MCP602-I/SN	Lower 100 μA supply current; rail-to-rail input/output; 2.8 MHz GBW; 2.5 mV V_IO; requires ≥2.7 V supply.	Better for ultra-low-power or rail-to-rail I/O needs; incompatible with 32 V single-supply operation.	Select when operating below 5.5 V or requiring full rail-to-rail swing on both input and output.

Compared with LM358DR and MCP602-I/SN, the AP358SL-13 uniquely balances 1 MHz bandwidth, ground-sensing capability, and 3–32 V single-supply flexibility - making it optimal for industrial +5 V or +24 V sensor interfaces where precision and supply robustness coexist.

FAQ

Is AP358SL-13 pin-compatible with standard SOIC-8 dual op amps like LM358?

Yes - AP358SL-13 uses the industry-standard SOP-8L (SOIC-8) pinout: Pin 1 = OUT1, Pin 2 = INV1, Pin 3 = NON-INV1, Pin 4 = GND, Pin 5 = NON-INV2, Pin 6 = INV2, Pin 7 = OUT2, Pin 8 = V+. This matches LM358, TL082, and other dual op amps in SOIC-8 packages, enabling drop-in replacement in most layouts.

Can AP358SL-13 operate from a 3.3 V supply?

Yes - the AP358SL-13 is specified for single-supply operation from 3 V to 32 V. At 3.3 V, it maintains functional performance: input common-mode range includes ground, output swings to within ~20 mV of GND, and supply current remains ~500 μA. Full specifications apply at 25°C; minimum operating voltage is 2.3 V.

Does AP358SL-13 support rail-to-rail input or output?

It supports rail-to-ground output (0 V to V₊ − 1.5 V) and ground-inclusive input common-mode range (0 V to V₊ − 1.5 V), but not full rail-to-rail input - the upper input limit is V₊ − 1.5 V. Input differential voltage can exceed V₊ safely. Output does not swing to V₊, limiting high-side dynamic range in some configurations.

What is the maximum capacitive load the AP358SL-13 can drive stably?

The AP358SL-13 can drive up to 50 pF capacitively in worst-case unity-gain non-inverting configuration without oscillation. For larger loads (e.g., >100 pF), add a series isolation resistor (10–100 Ω) between output and load, or use higher closed-loop gain (≥10×) to restore phase margin and ensure stability.
