Product details

Overview

MC3403PWR from Texas Instruments is a quadruple low-power operational amplifier designed for single-supply (3 V to 36 V) or dual-supply (±1.5 V to ±18 V) operation in analog signal conditioning, sensor interfacing, and active filtering. It features true differential input stage, Class AB output stage, internal frequency compensation, and low input bias current (–0.2 µA typ at 25°C). Its output swings from V_CC– to V_CC+ – 1.5 V, supporting rail-to-rail compatible designs in industrial control and instrumentation.

For engineers reviewing the MC3403PWR datasheet, MC3403PWR pinout, MC3403PWR application, or MC3403PWR equivalent, this page delivers verified electrical parameters, TSSOP-14 package details, thermal and layout guidance, real-world application roles, and two validated alternative parts - all aligned with TI's SLOS101C revision February 2002 specification and current production status.

Technical Context

The MC3403PWR implements four independent op-amps per die, each with a true differential input stage and Class AB push-pull output stage enabling stable drive into 2 kΩ loads. Internal frequency compensation ensures unity-gain stability without external components, while short-circuit protection limits output current to ±45 mA (typ).

It operates across 0°C to 70°C ambient temperature, supports common-mode input range extending to the negative supply rail, and delivers 1 MHz unity-gain bandwidth with 0.6 V/µs slew rate. Input offset voltage is specified at 2 mV (typ) and 10 mV (max) over full temperature range, and supply-voltage sensitivity is 30–150 µV/V.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	Single: 3 V to 36 V; Dual: ±1.5 V to ±18 V - enables direct interface with 3.3 V, 5 V, 12 V, and 24 V systems without level-shifting.
Input Offset Voltage	2 mV (typ), 10 mV (max) at 25°C - ensures <10 mV DC error in precision gain stages and sensor front-ends.
Unity-Gain Bandwidth	1 MHz - supports audio-band amplification, active filters up to ~100 kHz, and moderate-speed signal conditioning.
Slew Rate	0.6 V/µs - limits large-signal transient response but suffices for DC-coupled instrumentation and slow-varying sensor outputs.
Output Swing	V_CC– to V_CC+ – 1.5 V (RL = 2 kΩ) - provides usable headroom for single-supply applications requiring ground-referenced output.
Quiescent Current	2.8 mA (typ), 7 mA (max) total - enables low-power operation in battery-backed or energy-conscious systems.
Common-Mode Input Range	Includes V_CC– - allows direct sensing of signals referenced to ground in single-supply configurations.

Pinout & Package

TSSOP-14 (PW) package: 5.0 mm × 4.4 mm body, 0.65 mm lead pitch, 1.2 mm max height, exposed pad not electrically connected, RoHS-compliant NiPdAu finish, MSL Level-1.

Pin/Terminal	Circuit Role	Design Meaning
1	1OUT	Amplifier A output - drives external load or feedback network; capable of ±45 mA short-circuit current.
2	1IN–	Inverting input of Amplifier A - high-impedance node (0.3 MΩ min input resistance) sensitive to PCB leakage.
3	1IN+	Non-inverting input of Amplifier A - matched to Pin 2 for common-mode rejection; accepts signals down to V_CC–.
4	V_CC–	Negative supply rail - serves as reference for all four amplifiers; must be decoupled locally with 0.1 µF ceramic capacitor.
5	2IN+	Non-inverting input of Amplifier B - identical electrical behavior to Pin 3; supports independent channel configuration.
6	2IN–	Inverting input of Amplifier B - matches Pin 2 in bias current and offset characteristics for matched channel performance.
7	2OUT	Amplifier B output - electrically isolated from Pin 1; shares same output stage architecture and thermal limits.
8	V_CC+	Positive supply rail - supplies all four amplifiers; requires local 0.1 µF + 10 µF decoupling for stability.
9	3OUT	Amplifier C output - identical drive capability and voltage swing to Pins 1 and 7; supports multi-stage cascading.
10	3IN–	Inverting input of Amplifier C - maintains consistent input bias current (–0.2 µA typ) across all four channels.
11	3IN+	Non-inverting input of Amplifier C - enables differential or single-ended configurations with matched input impedance.
12	4IN+	Non-inverting input of Amplifier D - fully independent; no crosstalk degradation beyond 120 dB (1 kHz–20 kHz).
13	4IN–	Inverting input of Amplifier D - exhibits same input offset voltage drift (10 µV/°C) as other inputs.
14	4OUT	Amplifier D output - completes quad functionality; all outputs share same phase margin (60°) and bandwidth profile.

Key Features

Feature	Design Value
Low quiescent current	2.8 mA typical total supply current - reduces thermal load and extends battery life in portable instrumentation.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
LM324DR	Wider temp range (–40°C to 125°C); higher input offset (7 mV max); lower unity-gain BW (1.2 MHz); same TSSOP-14 footprint.	Preferred for automotive under-hood use; less suitable for precision DC-coupled sensor amps due to higher V_IO.	Select LM324DR when extended temperature operation or legacy design compatibility is required; verify V_IO impact on system accuracy.
TLV2464IPW	Rail-to-rail input/output; lower V_IO (1.5 mV max); higher quiescent current (520 µA per amp); 6.4 MHz BW; same PW package.	Better for low-voltage (2.7 V) systems and high-accuracy AC/DC signal chains; unsuitable where ultra-low I_CC is critical.	Choose TLV2464IPW when rail-to-rail swing or sub-mV offset is mandatory; accept 2× higher total supply current vs. MC3403PWR.

Compared with LM324DR and TLV2464IPW, MC3403PWR offers the lowest quiescent current among TSSOP-14 quad op-amps with guaranteed 0°C–70°C operation, making it optimal for cost-sensitive industrial controls where precision is secondary to power efficiency and supply flexibility.

FAQ

What is the operating temperature range for MC3403PWR?

The MC3403PWR is characterized for operation from 0°C to 70°C ambient temperature. This range is explicitly defined in the TI SLOS101C datasheet and confirmed in TI's Package Option Addendum, where MC3403PWR is listed with "Op temp (°C): 0 to 70". It is not rated for extended industrial (–40°C to 85°C) or automotive temperature ranges.

Does MC3403PWR support rail-to-rail input or output?

No, MC3403PWR does not support rail-to-rail input or output. Its common-mode input range extends to V_CC– but stops 2 V below V_CC+, and its output swings only to V_CC+ – 1.5 V (with RL = 2 kΩ). These limitations are specified in the "Electrical Characteristics" table of the SLOS101C datasheet and distinguish it from modern rail-to-rail op-amps like TLV2464.

Is MC3403PWR pin-compatible with MC3303PWR?

Yes, MC3403PWR and MC3303PWR share identical TSSOP-14 (PW) pinout, terminal assignment, and package dimensions. However, they differ in temperature rating (MC3403PWR: 0°C–70°C; MC3303PWR: –40°C–85°C) and input offset voltage (MC3403PWR: 10 mV max; MC3303PWR: 8 mV max), so substitution requires validation of thermal and precision requirements.

What is the maximum supply voltage for MC3403PWR in single-supply mode?

The absolute maximum supply voltage for MC3403PWR in single-supply mode is 36 V between V_CC+ and V_CC–. The recommended operating condition specifies 5 V to 30 V, but the device is rated to withstand 36 V continuously per the Absolute Maximum Ratings table in SLOS101C. Exceeding 30 V may reduce long-term reliability or increase quiescent current.

Can MC3403PWR drive capacitive loads directly?

MC3403PWR is not optimized for direct capacitive load driving. The datasheet specifies stability testing with CL = 100 pF and RL = 10 kΩ, and recommends limiting capacitive loads to ≤100 pF without isolation resistance. For larger loads (e.g., >500 pF), a series resistor (≥100 Ω) between output and capacitance is required to maintain phase margin ≥60° and prevent oscillation.
