Product details
Overview
LT1014DSW#TRPBF from Analog Devices (formerly Linear Technology) is a precision quad operational amplifier in 16-lead plastic SOIC (SW) package, featuring 50 µV max input offset voltage, 0.3 µV/°C drift, 117 dB CMRR, 120 dB PSRR, and rail-to-rail output swing to ground on single 5V supply. It serves as a drop-in upgrade for LM324/LM348 in instrumentation signal conditioning, thermocouple amplification, and 4–20 mA loop transmitters.
For engineers reviewing the LT1014DSW#TRPBF datasheet, LT1014DSW#TRPBF pinout, LT1014DSW#TRPBF application, or LT1014DSW#TRPBF equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in single-supply precision analog systems, and confirmed alternative options with documented functional trade-offs.
Technical Context
The LT1014DSW#TRPBF integrates four independent high-gain (8 million typical), low-noise op amps sharing a common substrate but with >120 dB channel separation at DC. Its all-NPN output stage enables true ground-sinking capability (≤4 mV saturation voltage at 1 mA) without crossover distortion-critical for single-supply sensor interfaces.
Input stage includes 400 Ω series protection resistors and proprietary phase-reversal prevention circuitry (Q21–Q28), allowing inputs to safely operate 5 V below ground while maintaining output polarity integrity-unlike LM324 or OP-221.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 50 µV typ / 150 µV max - enables sub-100 µV system-level offset budgets in strain gauge bridges |
| Offset Drift | 0.3 µV/°C typ / 2 µV/°C max - ensures <150 µV total drift over 0°C to 70°C industrial range |
| CMRR | 117 dB typ - rejects >70 mV common-mode error at 10 V input, critical for thermocouple cold-junction compensation |
| PSRR | 120 dB typ - maintains gain stability despite ±100 mV supply ripple in battery-powered instruments |
| Output Swing (Low) | ≤4 mV above ground at 1 mA sink - allows direct interfacing to ADC reference rails without level-shifting |
| Supply Current | 350 µA per amplifier - supports 650 µA average current in sampled-strain-gauge systems (TA08) |
| Gain-Bandwidth | 0.4 V/µs slew rate - sufficient for 10 kHz active filters and 300 Hz flowmeter linearization (TA06) |
| Input Noise | 0.55 µVP-P (0.1–10 Hz) - preserves 16-bit ENOB in 20 mV full-scale thermocouple outputs |

| 9 | OUTPUT D | Amplifier D output - dedicated to cold-junction compensation or linearization circuits (TA15) |
| 10 | –IN D | Inverting input of Amp D - referenced to LT1004 1.2 V bandgap for RTD biasing |
| 11 | +IN D | Non-inverting input of Amp D - receives temperature-compensated reference in platinum RTD conditioners |
| 12 | V– | Negative supply rail - tied to ground for single-supply operation; supports –15 V in dual-rail mode |
| 13 | +IN C | Non-inverting input of Amp C - used for zero-trim or gain-setting in multi-op-amp signal chains |
| 14 | –IN C | Inverting input of Amp C - configured as integrator or filter node in anemometer applications (TA05) |

Applications
| Battery-Powered Precision Instrumentation | Thermocouple Amplifiers |
|---|---|
Use Scenario: Portable pH meters and handheld multimeters operating from 9 V batteries with <1 mA average quiescent current. IC Role / Device Role / Timing Role: LT1014DSW#TRPBF acts as front-end signal conditioner, performing rail-to-rail buffering, offset trimming, and low-pass filtering before ADC sampling. Use Value: 350 µA per amplifier enables >200-hour battery life; ground-swing output eliminates level-shifter ICs, reducing BOM count by one component. | Use Scenario: Industrial temperature monitoring using Type K thermocouples across 0°C to 60°C ambient, requiring ±1°C cold-junction compensation accuracy. IC Role / Device Role / Timing Role: LT1014DSW#TRPBF implements three-channel thermometer (TA02) with dedicated amps for thermocouple gain, reference buffering, and cold-junction compensation. Use Value: 117 dB CMRR rejects EMI-induced common-mode errors on long sensor cables; guaranteed 150 µV offset ensures <0.5°C measurement uncertainty at 100°C. |
| 4–20 mA Current Loop Transmitters | Active Filters |
Use Scenario: Field-mounted pressure transmitters converting 0–350 psi into fully floating 4–20 mA outputs compliant with HART physical layer. IC Role / Device Role / Timing Role: LT1014DSW#TRPBF configures as precision current source (TA13/TA14), with one amp regulating sense voltage and another driving the pass transistor. Use Value: 120 dB PSRR prevents supply ripple from modulating loop current; 0.3 µV/°C drift limits temperature-induced span error to <0.02% over 0°C–70°C. | Use Scenario: Anti-aliasing and reconstruction filters in data acquisition systems sampling at 10 kHz with 80 dB stopband attenuation. IC Role / Device Role / Timing Role: LT1014DSW#TRPBF implements multiple feedback stages in Sallen-Key and state-variable topologies (TA07, TA18). Use Value: 0.4 V/µs slew rate supports 10 kHz unity-gain bandwidth; 123 dB channel separation prevents crosstalk between adjacent filter sections. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP4177ARUZ | Lower offset (60 µV max), higher cost, 3.6 MHz GBW vs 0.4 V/µs slew rate | Better for high-speed precision DAC buffers; less suitable for low-power battery systems due to 1.2 mA supply current | Select OP4177ARUZ only when >100 kHz signal bandwidth is required and power budget allows ≥4.8 mA total quiescent current |
| TLV2464IDR | Higher offset (2000 µV max), rail-to-rail I/O, 650 µA supply current, 0.6 V/µs slew rate | Acceptable for cost-sensitive consumer sensors where 12-bit accuracy suffices; lacks phase-reversal protection | Choose TLV2464IDR for non-critical applications like appliance controls where sub-100 µV offset is unnecessary and BOM cost is primary constraint |
Compared with OP4177ARUZ and TLV2464IDR, LT1014DSW#TRPBF uniquely balances ultra-low offset (150 µV max), ground-sinking capability, phase-reversal immunity, and 350 µA quiescent current-making it optimal for battery-powered, safety-critical analog front-ends where precision and robustness coexist under tight power constraints.

FAQ
What is the maximum operating temperature range for LT1014DSW#TRPBF?
The LT1014DSW#TRPBF is rated for 0°C to 70°C ambient operation (Commercial grade). This is explicitly defined in the Order Information table on page 3 of the datasheet, where "LT1014DSW#TRPBF" is listed with "0°C to 70°C" under Temperature Range. It does not meet Industrial (–40°C to 85°C) or Military (–55°C to 125°C) specifications.
Does LT1014DSW#TRPBF support true single-supply operation with input and output referenced to ground?
Yes, LT1014DSW#TRPBF supports true single-supply operation: its input common-mode range extends to ground (0 V), and its output can swing to within 4 mV of ground while sinking 1 mA. This is confirmed in the Applications Information section (page 9), which states "input common mode range includes ground; the output can also swing to within a few millivolts of ground," and is validated in Electrical Characteristics tables for 5 V supply conditions.
Is LT1014DSW#TRPBF pin-compatible with standard 14-pin DIP quad op amps like LM324?
No, LT1014DSW#TRPBF is not pin-compatible with 14-pin DIP packages such as LM324. It uses a 16-pin SOIC (SW) footprint with two no-connect (NC) pins (Pins 8 and 16) and different pin assignments (e.g., V– on Pin 12 instead of Pin 4). However, the datasheet states it "directly upgrades designs in the industry standard 14-pin DIP LM324/LM348… pin configuration" via functional equivalence-not mechanical compatibility-requiring PCB redesign or adapter boards.
What is the guaranteed input offset voltage specification for LT1014DSW#TRPBF?
The guaranteed input offset voltage for LT1014DSW#TRPBF is 150 µV maximum at 25°C, as specified for the "LT1014AC" grade in the Electrical Characteristics table (page 4). This value applies to the Commercial temperature range (0°C to 70°C) and is tested per production lot-distinct from the 50 µV typical value, which is not guaranteed.
Can LT1014DSW#TRPBF be used in comparator applications?
Yes, LT1014DSW#TRPBF is explicitly qualified for comparator use in single-supply systems, as stated in the Applications Information section (page 10): "The single supply operation… lends itself to its use as a precision comparator with TTL compatible output." Its fast recovery from saturation (illustrated in TPC15–TPC18), low input bias current (12 nA max), and phase-reversal immunity make it suitable for threshold detection in 4–20 mA transmitters (TA13/TA14) and methane detectors (TA11).
