Detailed Description

NJM4558V-TE1 is a dual bipolar operational amplifier designed for general-purpose and audio use. It is internally frequency-compensated, unity-gain stable, and offers low noise with solid DC performance. This version comes in a compact TSSOP-8 package for space‑constrained designs. Main Category: Integrated Circuits (ICs). Small Classification: Specialized ICs.

Key Features

Dual op-amp with internal compensation and unity-gain stability

Wide supply range usable in ±4 V to ±18 V systems (typical; check datasheet)

Low input offset voltage (around a few mV typical)

Low input bias current (around sub-μA to μA typical for bipolar input)

Moderate slew rate around 1 V/μs typical

Gain-bandwidth around 1 MHz typical for general-purpose applications

High open-loop gain around 100 dB typical

Good audio performance with low distortion in practical circuits

Standard 8-pin pinout for easy replacement and drop-in designs

Tape-and-reel TE1 packaging for automated assembly

Key Advantages

Proven, workhorse dual op-amp for audio, instrumentation, and signal conditioning

Stable and easy to design with; minimal external components

Broad ecosystem and many pin-compatible options for second‑source flexibility

Compact TSSOP-8 saves PCB area while maintaining performance

Reliable operation over a wide supply range and temperatures

Packaging

Type: TSSOP-8 surface-mount

Manufacturer package code: 836 (vendor code for TSSOP-8 variant)

Material: Epoxy-molded body with copper leads, typical NiPdAu or Sn plating

Size: Approx. 4.4 mm x 3.0 mm body, height ~1.0 mm max (typical TSSOP-8)

Pin pitch: 0.65 mm, 8 leads

Pin configuration:

1 Output A

2 Inverting input A

3 Non-inverting input A

5 Non-inverting input B

6 Inverting input B

7 Output B

8 V+ (positive supply)

Thermal characteristics: θJA typically in the 130–180 °C/W range depending on PCB and airflow; ensure adequate copper area and thermal design

Electrical properties (typical values; verify with datasheet):

Supply voltage operation around ±4 V to ±18 V

Input offset around 1–5 mV typical

Input bias current around 0.5–2 μA typical

Slew rate around 1 V/μs

Unity gain bandwidth around 1 MHz

Output swing to within approximately 2 V of rails at ±15 V supply

Lifecycle

General status: NJM4558 family is widely used and typically available in multiple packages; no public EOL notice is commonly cited for this variant at the time of writing. For the most up-to-date lifecycle status, please contact Y-IC.

Pin-compatible or alternative models to consider:

JRC4558D (NJR) DIP/SOIC variants of the same family

RC4558 (Texas Instruments) dual bipolar op-amp, widely used

KA4558 (ON Semiconductor / Fairchild legacy) dual bipolar op-amp

MC1458 (various manufacturers) classic dual op-amp, similar function with older specs

NE5532 (various) dual low-noise audio op-amp, better performance but different input characteristics

NJM4580 (NJR) dual audio op-amp with improved noise/distortion

NJM2068 (NJR) dual low-noise, low-distortion audio op-amp

TL072/TL082 (Texas Instruments) dual JFET-input op-amps, different input technology and characteristics

Notes: While many of the above are pin-compatible in 8-pin packages, electrical behavior differs (noise, bias current, supply range, distortion). Always review the datasheet and test in your circuit. If you need a direct, drop-in recommendation for your exact operating conditions, contact our sales team through the Y-IC website.
