Product details
Overview
OPA593DNTT from Texas Instruments is a high-voltage (85 V), precision power operational amplifier with 250 mA continuous output current, ±20 µV offset voltage, 10 MHz gain-bandwidth product, and rail-to-rail output-designed for semiconductor test equipment requiring stable high-current sourcing/sinking under wide supply and temperature ranges.
For engineers reviewing the OPA593DNTT datasheet, OPA593DNTT pinout, OPA593DNTT application, or OPA593DNTT equivalent, this page delivers verified specifications, thermal flag behavior, current-limit resistor configuration, disable timing (12 µs), and real-world settling performance (2.9 µs to ±0.01%) critical for programmable DC power supplies and medical imaging front-ends.
Technical Context
The OPA593DNTT integrates laser-trimmed input stage circuitry to achieve ±20 µV offset and ±0.4 µV/°C drift, eliminating system-level calibration. Its mux-friendly inputs support full rail-to-rail common-mode range and fast settling in multichannel test systems.
It implements dual status flags (pin 7 for overcurrent, pin 8 for overtemperature), an external current-limit resistor interface (pin 11), and enable/disable control via pins 1 and 12 referenced to E/D Com (pin 1). The thermal pad is internally connected to V– and must be soldered to PCB ground.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 8 V to 85 V (±4 V to ±42.5 V); supports single- or dual-supply operation in high-voltage test fixtures |
| Output Current | ±250 mA continuous; drives FET-based current boost stages or direct loads like LCD bias circuits |
| Offset Voltage | ±20 µV typical; enables sub-mV accuracy in precision reference buffers without trimming |
| Gain-Bandwidth | 10 MHz; sustains stable closed-loop gain up to 100× at 100 kHz for fast transient response |
| Slew Rate | 45 V/µs (rising); achieves 70-V step response in <2 µs for high-dV/dt applications |
| Quiescent Current | 3.25 mA enabled / 250 µA disabled; low-power standby mode reduces thermal load during idle cycles |
| Operating Temp | –40°C to +125°C; qualified for industrial and medical scanner environments with thermal flag monitoring |
Pinout & Package
Package: 12-pin WSON (DNT), 4.00 mm × 4.00 mm body size, exposed thermal pad internally tied to V– (pin 6).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| E/D Com (1) | Enable reference | Common reference for enable/disable logic; must be biased between V– and (V+) – 6 V |
| E/D (12) | Enable control | High = enabled (E/D ≥ E/D Com + 1.5 V); low = disabled (E/D ≤ E/D Com + 0.5 V) |
| –IN (3), +IN (4) | Differential inputs | Mux-friendly: tolerate input voltages beyond rails by 0.3 V with current limiting |
| ILIMIT (11) | Current limit set | Resistor-connected to V– sets accurate ±25–250 mA limit per current-limit equation |
| V+ (10), V– (6) | Power rails | Support 85-V total supply; thermal pad must be soldered to V–-referenced PCB copper |
| OUT (9) | Amplifier output | Rail-to-rail swing: within 25 mV of rails at no load; 1.2–2 V headroom at ±250 mA |
| Current Flag (7) | Status output | Open-drain active-high flag; asserts within 10 µs of overcurrent event |
| Thermal Flag (8) | Status output | Open-drain active-high flag; triggers at 170°C junction, clears at 150°C |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed offset | ±20 µV typical offset and ±0.4 µV/°C drift eliminate factory calibration in production test systems |
| Configurable current limit | External resistor on ILIMIT pin provides ±25–250 mA limit with ±13% accuracy at 250 mA |
| Dual status flags | Independent open-drain outputs for overcurrent (pin 7) and overtemperature (pin 8) enable fault-isolation in safety-critical power stages |
| Disable function | 12 µs disable time places output in high-Z state and cuts quiescent current to 250 µA for power-gated operation |
| Mux-friendly inputs | Input common-mode range extends to rails (V– – 0.1 V to V+ – 3.5 V), enabling seamless channel switching in automated test equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage, high-precision power op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA454AIDDA | Wider supply (100 V), lower output current (70 mA), no current-limit pin or thermal flag | Best for ultra-high-voltage, low-current precision buffering where fault reporting is not required | Select when >85 V operation is mandatory and 250 mA output is unnecessary |
| LM675T/NOPB | Lower supply (60 V), higher quiescent current (10 mA), no laser trimming (±10 mV offset), no status flags | Suitable for cost-sensitive industrial power stages where ±10 mV offset is acceptable | Select only for non-precision, non-fault-tolerant 250 mA drivers with <60 V rails |
Compared with OPA454AIDDA and LM675T/NOPB, the OPA593DNTT uniquely combines 85-V operation, 250-mA output, laser-trimmed precision, and dual fault flags-making it the only choice for programmable power supplies needing both accuracy and embedded diagnostics.

FAQ
What is the maximum continuous output current specification for the OPA593DNTT?
The OPA593DNTT delivers ±250 mA continuous output current when configured with RCL = 2.29 kΩ and VS = 85 V. This rating applies across the full operating temperature range (–40°C to +125°C) and is verified with specified current-limit accuracy. Output current capability decreases slightly at higher temperatures or lower supply voltages, as shown in Figures 6-19 through 6-30 of the datasheet.
How does the current-limit function work on the OPA593DNTT?
The OPA593DNTT uses an external resistor (RCL) connected between the ILIMIT pin (11) and V– (6) to set the current limit. The relationship follows the equation: ILIMIT = (3.687 V × 4000) / (56.7 kΩ + RCL). For example, a 2.29 kΩ resistor yields ~250 mA. Accuracy is ±13% at 250 mA, and the Current Flag (pin 7) asserts within 10 µs of overcurrent detection.
Does the OPA593DNTT support rail-to-rail input operation?
No-the OPA593DNTT features mux-friendly inputs with extended common-mode range (V– – 0.1 V to V+ – 3.5 V), but it does not support true rail-to-rail input. However, its input stage tolerates signals beyond the supply rails by up to 0.3 V when current-limited, enabling safe operation in multiplexed test systems where input transients may exceed rails.
What is the purpose of the thermal pad on the OPA593DNTT package?
The exposed thermal pad on the OPA593DNTT's 12-pin WSON (DNT) package is internally connected to V– (pin 6) and must be soldered to a PCB copper area tied to the negative supply rail. This connection provides critical thermal dissipation (RθJB = 17.8 °C/W) and ensures reliable operation at full output current; omitting this connection risks thermal shutdown or reduced lifetime.
Can the OPA593DNTT be used in single-supply configurations?
Yes-the OPA593DNTT operates from a single supply as low as 8 V (e.g., V+ = 8 V, V– = GND). Its rail-to-rail output and wide input common-mode range (down to V– – 0.1 V) support true single-supply use. When using single supply, ensure the E/D Com pin (1) is referenced appropriately (e.g., to GND or mid-rail), and verify that the ILIMIT resistor network and status flag pullups comply with the absolute maximum ratings for those pins.
