Product details
Overview
NE5234D/01,518 from Philips Semiconductors is a matched quad low-voltage operational amplifier with rail-to-rail input and output operation, 2.5 MHz unity-gain bandwidth, 0.8 V/µs slew rate, and 700 µA per amplifier supply current. It operates down to 1.8 V supply and delivers 5.5 VPP into 600 Ω - ideal for portable instrumentation and automotive signal conditioning.
For engineers reviewing the NE5234D/01,518 datasheet, NE5234D/01,518 pinout, NE5234D/01,518 application, or NE5234D/01,518 equivalent, key selection criteria include rail-to-rail I/O capability at 1.8–5.5 V single supply, matched amplifier offset (≤0.4 mV typical), 25 nV/√Hz input voltage noise, and SO14 package thermal resistance of 115 °C/W.
Technical Context
The NE5234D/01,518 integrates four precision op-amps on a single die with matched DC characteristics: offset voltage difference ≤0.4 mV and input bias current difference ≤25 nA between amplifiers. Its input stage supports common-mode voltage 250 mV beyond both rails, enabling true single-supply sensor interfacing.
Output inversion prevention circuitry eliminates phase reversal during input overdrive - a critical feature for closed-loop motor drive error amplifiers and transducer buffers where signal polarity integrity must be preserved across full input range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2 V to +5.5 V single supply; ±1 V to ±2.75 V dual supply - enables direct interface with 3.3 V and 5 V logic systems without level-shifting. |
| Unity-Gain Bandwidth | 2.5 MHz - supports stable gain-of-1 signal buffering up to ~200 kHz with <1% settling in 1.4 µs. |
| Input Voltage Noise | 25 nV/√Hz at 1 kHz - suitable for low-level sensor amplification where thermal noise dominates. |
| Output Swing | Within 50 mV of both rails - delivers >98% of full supply swing into high-impedance loads, maximizing dynamic range in low-voltage systems. |
| Offset Voltage Match | ≤0.4 mV max difference between any two amplifiers - ensures consistent gain and common-mode rejection in multi-channel instrumentation. |
| Slew Rate | 0.8 V/µs - limits large-signal distortion in audio and datacom bus drivers operating near 10 kHz fundamental frequencies. |
Pinout & Package
NE5234D/01,518 is housed in a 14-pin plastic small outline (SO) package per SOT108-1, 3.9 mm body width, with standard SOIC thermal and mechanical footprint.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-voltage rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV324DR | Lower bandwidth (1 MHz), higher input bias current (100 nA), no guaranteed offset matching between amplifiers. | Not suitable for multi-channel matched gain stages; acceptable for basic signal conditioning where cost is primary. | Select LMV324DR only when rail-to-rail I/O is required but amplifier matching and noise performance are non-critical. |
| TLV2464CDR | Higher quiescent current (650 µA per amp vs. 700 µA), better offset drift (0.5 µV/°C vs. 4 µV/°C), but no output inversion prevention. | Lacks phase-reversal immunity - unsuitable for motor drive error amplifiers with possible input overvoltage conditions. | Choose TLV2464CDR for ultra-low-drift applications where output inversion risk is absent, but avoid in closed-loop power control. |
Compared with LMV324DR and TLV2464CDR, the NE5234D/01,518 uniquely combines matched amplifier performance, output inversion prevention, and 25 nV/√Hz noise in a single SO14 package - making it optimal for precision multi-channel sensing where signal integrity and DC accuracy are co-dependent.

FAQ
What is the operating temperature range for the NE5234D/01,518?
The NE5234D/01,518 is rated for 0 °C to +70 °C operation, consistent with the NE5234 grade designation. This range is validated across all DC and AC specifications including offset voltage, bandwidth, and output swing - ensuring reliable performance in commercial and automotive under-hood environments where ambient temperatures remain below 70 °C.
Does the NE5234D/01,518 support true rail-to-rail input and output operation?
Yes, the NE5234D/01,518 supports rail-to-rail input with common-mode voltage extending 250 mV beyond both supply rails, and rail-to-rail output with swing within 50 mV of VCC and GND across the full supply range. This is confirmed in the datasheet's DESCRIPTION and DC ELECTRICAL CHARACTERISTICS sections for the NE5234D/01,518 variant.
What is the maximum supply voltage the NE5234D/01,518 can tolerate?
The NE5234D/01,518 has an absolute maximum single-supply voltage rating of 7 V. However, the recommended operating range is +2 V to +5.5 V. Operation above 5.5 V is not characterized and may compromise parametric guarantees such as offset voltage, CMRR, and output swing - so the NE5234D/01,518 should not be used beyond 5.5 V in production designs.
How does output inversion prevention work in the NE5234D/01,518?
The NE5234D/01,518 incorporates internal circuitry that clamps the differential input stage during overdrive, preventing the output from reversing polarity when input exceeds common-mode limits. As shown in Figure 2 of the datasheet, this behavior is intrinsic to the NE5234D/01,518 silicon design and requires no external components - distinguishing it from conventional op-amps like the NE5532.
Is the NE5234D/01,518 pin-compatible with other quad op-amps in SO14 packages?
No - the NE5234D/01,518 uses a non-standard pinout optimized for matched quad operation: pins 1–3 and 5–7 serve Amp1/Amp2, while pins 8–10 and 12–14 serve Amp3/Amp4, with VCC (pin 4) and GND (pin 11) centrally located. This differs from industry-standard SO14 quad op-amps like LM324 or TL084, so PCB layout must follow the NE5234D/01,518-specific pin configuration.
