Product details
Overview
LF353M/NOPB from Texas Instruments is a dual JFET-input operational amplifier with 4 MHz gain bandwidth, 13 V/μs slew rate, and 10 mV max input offset voltage. It delivers low input bias current (50 pA typ), high input impedance (10¹² Ω), and low THD (≤0.02%) for precision analog signal conditioning in industrial instrumentation and audio tone control circuits.
For engineers reviewing the LF353M/NOPB datasheet, LF353M/NOPB pinout, LF353M/NOPB application, or LF353M/NOPB equivalent, key selection criteria include JFET-input noise performance (25 nV/√Hz), common-mode voltage range (±11 V), output swing (±12 V into 10 kΩ), and SOIC-8 thermal derating (160°C/W junction-to-ambient).
Technical Context
The LF353M/NOPB uses BI-FET II technology with internally trimmed JFET input stages, enabling rail-to-rail common-mode operation up to ±11 V and stable DC-coupled performance across 0°C to +70°C. Its zener-biased internal circuitry supports operation down to ±6 V supplies while maintaining functional gain bandwidth.
Each amplifier operates independently with matched input characteristics-typical input bias current drift is 10 μV/°C and input offset current remains below 100 pA over temperature-making it suitable for dual-channel integrators, sample-and-hold circuits, and active filter topologies requiring channel-to-channel tracking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 4 MHz typical - enables stable unity-gain compensation and usable closed-loop bandwidth up to ~300 kHz at gain = 10. |
| Slew Rate | 13 V/μs typical - supports fast transient response in D/A output buffers and pulse amplification without distortion. |
| Input Offset Voltage | 10 mV max - ensures ≤0.1% error in 10 V full-scale measurement paths without external nulling. |
| Input Bias Current | 50 pA typical - minimizes voltage error across high-impedance sensor interfaces (e.g., photodiode transimpedance amps). |
| Common-Mode Input Range | ±11 V at ±15 V supply - allows direct interfacing with bipolar signal sources without level-shifting circuitry. |
| Output Voltage Swing | ±12 V into 10 kΩ - provides >80% of rail-to-rail swing for dynamic range preservation in line-level audio and data acquisition. |
| Total Harmonic Distortion | ≤0.02% at 1 kHz - meets fidelity requirements for active tone controls and low-distortion preamplifier stages. |
Pinout & Package
LF353M/NOPB is housed in an 8-pin SOIC (D package) with standard dual op-amp pinout compatible with industry layout conventions. Thermal resistance is 160°C/W junction-to-ambient, requiring board-level copper area for sustained 3.6 mA supply current dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Inverting amplifier output stage; capable of sourcing/sinking ≥10 mA into 2 kΩ load. |
| 2 | Inverting Input A | High-impedance JFET gate node; differential input voltage limit ±30 V independent of supply rails. |
| 3 | Non-Inverting Input A | Matched to Pin 2 for <100 pA input offset current; common-mode range extends to ±11 V. |
| 4 | V– | Negative supply connection; must not be exceeded by either input voltage to prevent latch-up. |
| 5 | Non-Inverting Input B | Independent second channel input; identical DC/AC specs to Channel A per datasheet matching. |
| 6 | Inverting Input B | Second channel inverting input; supports separate feedback networks without crosstalk (−120 dB coupling). |
| 7 | Output B | Second independent output; fully specified for ±12 V swing and 2 μs 0.01% settling time. |
| 8 | V+ | Positive supply connection; supports ±6 V to ±18 V dual-rail operation with functional GBW retention down to ±6 V. |
Key Features
| Feature | Design Value |
|---|---|
| Internally trimmed offset voltage | 10 mV max eliminates need for external nulling potentiometers in production-grade instrumentation. |

| Fast 0.01% settling time | 2 μs supports accurate sampling in 500 kSPS data acquisition systems with minimal aperture uncertainty. |
| High CMRR | 100 dB typical rejects power supply ripple and EMI in single-ended sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L2CD | Lower supply current (1.4 mA), lower GBW (1.7 MHz), higher input offset (15 mV max) | Better suited for battery-powered low-speed sensing where power budget <2 mA is critical | Select TLC27L2CD only when supply current is prioritized over speed and precision; not drop-in due to lower slew rate (0.04 V/μs). |
| TL072CP | Higher slew rate (13 V/μs same), lower input bias (65 pA typ), but no internal offset trim (15 mV max) | Requires external nulling for DC-critical applications; better noise performance (18 nV/√Hz) | Choose TL072CP when lowest noise is required and board space allows offset nulling; pin-compatible but not functionally identical. |
Compared with LF353M/NOPB, TLC27L2CD trades bandwidth and precision for ultra-low power, while TL072CP offers superior noise and matching at the cost of untrimmed offset-neither is pin- or spec-compatible without circuit validation.

FAQ
What is the maximum supply voltage rating for LF353M/NOPB?
The LF353M/NOPB has an absolute maximum supply voltage rating of ±18 V. Operation beyond this limit risks permanent damage to internal JFET structures. For reliable long-term use, TI specifies recommended operating conditions of ±15 V, with functional performance maintained down to ±6 V. The LF353M/NOPB must never be subjected to reverse polarity supply connections, as this can fuse internal conductors.
Does LF353M/NOPB support rail-to-rail input or output operation?
No, LF353M/NOPB does not support rail-to-rail input or output operation. Its input common-mode voltage range is limited to ±11 V with ±15 V supplies, and output swing is specified as ±12 V into 10 kΩ. Neither input nor output reaches within 3 V of either supply rail. This limitation is inherent to its JFET input stage and Class AB output architecture, as confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables of the official datasheet.
Is LF353M/NOPB pin-compatible with LM358 or LM1558?
The LF353M/NOPB is pin-compatible with the LM1558 but not with the LM358. Both LF353M/NOPB and LM1558 use identical 8-pin SOIC and PDIP footprints with matching pin functions (e.g., Pin 1 = Output A, Pin 2 = Inverting Input A). However, LM358 is a single-supply BJT-input op-amp with different pinout and electrical behavior-substituting LF353M/NOPB for LM358 requires full circuit revalidation due to differences in input structure, biasing, and common-mode range.
What is the thermal resistance (θJA) of LF353M/NOPB in SOIC-8 package?
The LF353M/NOPB in SOIC-8 (D package) has a typical junction-to-ambient thermal resistance (θJA) of 160°C/W, as documented in TI's packaging addendum and thermal design guidelines. This value assumes standard JEDEC 2-layer board conditions. To maintain safe junction temperature under continuous 3.6 mA supply current, PCB layout must include adequate copper pour on the exposed pad side and avoid enclosing the device in thermally isolated areas.
Can LF353M/NOPB drive capacitive loads directly without stability issues?
LF353M/NOPB is not unity-gain stable with purely capacitive loads exceeding ~100 pF. Its internal compensation is optimized for resistive loads; driving cables or ADC input capacitance directly may cause peaking or oscillation. TI recommends adding a series isolation resistor (typically 100–500 Ω) between LF353M/NOPB output and capacitive load, or using external compensation networks as detailed in the "Application Hints" section of the SNOSBH3F datasheet.
