Product details
Overview
NE5234D/01,512 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 delivers 5.5 VPP into 600 Ω and supports single-supply operation down to 1.8 V, making it suitable for portable instrumentation and automotive signal conditioning.
For engineers reviewing the NE5234D/01,512 datasheet, NE5234D/01,512 pinout, NE5234D/01,512 application, or NE5234D/01,512 equivalent, key selection criteria include rail-to-rail I/O capability at 2–5.5 V supply, matched amplifier offset (≤0.4 mV typical), 25 nV/√Hz input noise, and SO14 package thermal resistance of 115 °C/W.
Technical Context
The NE5234D/01,512 integrates four precision op-amps on a single die with matched transistor pairs ensuring tight offset voltage tracking (<0.4 mV typical between amplifiers) and low drift (4 µV/°C). Its input stage operates 250 mV beyond both rails, while the output swings within 50 mV of VCC and GND across the full 2–5.5 V supply range.
It features output inversion prevention circuitry that avoids phase reversal during common-mode overdrive - a critical reliability feature in sensor front-ends and motor error amplifiers. The device includes ESD protection (2000 V HBM), short-circuit protection, and is rated for 0 °C to +70 °C operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (550 µA per amp vs. 700 µA), lower noise (11 nV/√Hz), but no output inversion prevention. | Preferred where ultra-low noise dominates over fault tolerance; unsuitable for sensor inputs prone to overdrive. | Select TLV2464IDR only when noise budget is tighter than 20 nV/√Hz and overdrive events are absent. |
| LMV324DT | Lower bandwidth (1 MHz), higher offset (±3 mV), no rail-to-rail input; lacks inter-amplifier matching spec. | Suitable for cost-sensitive general-purpose amplification, not for precision multi-channel sensing. | Choose LMV324DT only for non-critical DC-coupled gain stages where matching and rail-to-rail operation are unnecessary. |
Compared with TLV2464IDR and LMV324DT, the NE5234D/01,512 uniquely combines rail-to-rail I/O, matched quad topology, output inversion prevention, and 2.5 MHz bandwidth - making it the only option among the three qualified for automotive sensor front-ends requiring simultaneous accuracy, fault resilience, and speed.

FAQ
What is the operating temperature range for the NE5234D/01,512?
The NE5234D/01,512 is rated for operation from 0 °C to +70 °C, as confirmed by its ordering code "NE" prefix and the Recommended Operating Conditions table in the Philips product data sheet. This distinguishes it from the SA5234D variant, which extends to –40 °C to +85 °C. The NE5234D/01,512's specifications - including offset voltage, CMRR, and supply current - are guaranteed across this commercial temperature range.
Does the NE5234D/01,512 support true rail-to-rail input and output?
Yes, the NE5234D/01,512 supports rail-to-rail input (common-mode range extends 250 mV beyond both rails) and rail-to-rail output (swings to within 50 mV of VCC and GND). This is explicitly verified in the DESCRIPTION section and DC ELECTRICAL CHARACTERISTICS table, where output voltage swing is specified as VEE+0.05 to VCC–0.05 at light load and VEE+0.2 to VCC–0.2 at 5 mA load - confirming full functionality across the 2–5.5 V supply range.
What is the maximum supply voltage the NE5234D/01,512 can tolerate?
The NE5234D/01,512 has an absolute maximum single-supply voltage of 7 V, as stated in the ABSOLUTE MAXIMUM RATINGS table. However, the RECOMMENDED OPERATING CONDITIONS specify a safe operating range of +2 V to +5.5 V. Operation above 5.5 V risks exceeding power dissipation limits and may compromise long-term reliability, even if below the 7 V absolute maximum.
How does the output inversion prevention feature work in the NE5234D/01,512?
The NE5234D/01,512 incorporates internal circuitry that prevents output phase reversal when the input common-mode voltage exceeds the supply rails - a failure mode common in conventional op-amps. As shown in Figure 2 of the datasheet, this is achieved via dedicated clamping and biasing networks that maintain correct polarity during overdrive. This behavior is guaranteed across the full temperature and supply range and is critical in closed-loop motor drive error amplifiers where inversion could cause catastrophic instability.
Is the NE5234D/01,512 pin-compatible with other quad op-amps in SO14 packages?
No - the NE5234D/01,512 uses a proprietary pinout optimized for matched quad operation and output inversion prevention, differing from industry-standard configurations like the LM324 or TL074. Its pin 1 is OUTPUT1 (not VCC), and pin 11 is GND (not V–), as confirmed in Figure 1. Substituting with generic quad op-amps would require PCB redesign. Always verify pin mapping against the NE5234D/01,512-specific schematic symbol before layout.
