Product details
Overview
OPA357AIDDARG3 from Texas Instruments is a single-channel, rail-to-rail input/output, 250-MHz unity-gain stable CMOS operational amplifier in SOT-23-6 package. It delivers 150 V/µs slew rate, 6.5 nV/√Hz input voltage noise, and >100 mA output drive-enabling high-fidelity video line driving, photodiode transimpedance amplification, and ADC/DAC buffering in space-constrained, low-voltage systems.
For engineers reviewing the OPA357AIDDARG3 datasheet, OPA357AIDDARG3 pinout, OPA357AIDDARG3 application, or OPA357AIDDARG3 equivalent, key selection criteria include its 2.5–5.5 V supply range, shutdown IQ < 6 µA, 0.02% differential gain error for NTSC video, and thermal shutdown protection at 160°C-critical for portable, optical, and industrial signal-chain designs.
Technical Context
The OPA357AIDDARG3 employs a complementary rail-to-rail input stage (N- and P-channel parallel pairs) enabling common-mode operation 100 mV beyond rails, and a Class AB rail-to-rail output stage delivering 100 mV swing from rails into 1-kΩ loads. Its voltage-feedback architecture supports unity-gain stability with 250 MHz small-signal bandwidth and 100 MHz gain-bandwidth product.
Integrated enable logic uses a Schmitt-trigger input with TTL-compatible thresholds (0.8 V low, 2.0 V high), achieving 100 ns turn-on and 30 ns turn-off times. Thermal shutdown activates at 160°C junction temperature and resets at 140°C, ensuring robust operation under overload or high ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 250 MHz - enables stable +1-V/V buffer operation for wideband signals up to 250 MHz without peaking or oscillation. |
| Slew Rate | 150 V/µs - supports clean 4-V step response in ≤30 ns, critical for fast-settling ADC drivers and pulse amplification. |
| Input Voltage Noise | 6.5 nV/√Hz at 1 MHz - preserves SNR in low-level sensor interfaces like photodiode transimpedance stages. |
| Output Current | >100 mA continuous - drives 75-Ω back-terminated video cables or laser diodes directly without external buffers. |
| Supply Range | 2.5 V to 5.5 V - operates from single Li-ion cells (3.0–3.7 V) or 3.3/5.0 V rails, simplifying power architecture. |
| Shutdown IQ | <6 µA - reduces system standby power by >99.8% vs active mode (4.9 mA), extending battery life in portable instruments. |
| Differential Gain/Phase | 0.02% / 0.09° (NTSC, RL = 150 Ω) - meets broadcast-grade video fidelity requirements without external compensation. |
Pinout & Package
SOT-23-6 package (2.90 mm × 1.60 mm body size), surface-mount, thermally enhanced with exposed pad (DBV variant). Pin 1 marked via dot; orientation per TI DBV top-view diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: Out | Amplifier output | Delivers rail-to-rail voltage swing; capable of ±100 mA continuous current into resistive loads. |
| 2: V− | Negative supply | Reference for single-supply operation (e.g., ground); supports common-mode input down to V− − 0.1 V. |
| 3: +In | Noninverting input | High-impedance CMOS node (10¹³ Ω || 2 pF); accepts signals up to V+ + 0.1 V and V− − 0.1 V. |
| 4: −In | Inverting input | Matches +In in bias current (3 pA typ) and noise; used for precision inverting configurations or feedback networks. |
| 5: Enable | Shutdown control | TTL-compatible digital input; low disables amplifier (IQ < 6 µA), high enables normal operation (4.9 mA). |
| 6: V+ | Positive supply | Accepts 2.5–5.5 V; powers internal bias circuitry and output stage; PSRR > 66 dB across 10 Hz–10 MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends 100 mV beyond supplies; output swings within 100 mV of rails into 1-kΩ - maximizes dynamic range in low-voltage systems. |
| Video-optimized performance | 0.02% differential gain / 0.09° differential phase error on 75-Ω NTSC loads - eliminates need for external video reconstruction filters. |
| Fast enable/disable | 100 ns turn-on / 30 ns turn-off - enables time-gated signal acquisition and multiplexed bus sharing without output glitches. |
| Thermal protection | Shuts down at 160°C junction temperature; resumes at 140°C - prevents permanent damage during sustained overload or poor PCB thermal design. |
| Low input bias current | 3 pA typical - minimizes offset drift and leakage errors in high-impedance sensor interfaces (e.g., photodiodes, piezoelectrics). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA354AIDDARG3 | No shutdown function; identical bandwidth (250 MHz), slew rate (150 V/µs), and noise (6.5 nV/√Hz). | Used where always-on operation is acceptable and board space allows omission of enable logic. | Select when shutdown is unnecessary and lowest possible quiescent current variation is required (no enable path leakage). |
| OPA355AIDBVR | 200-MHz GBW (vs 250 MHz), same shutdown, rail-to-rail output only (not input), higher input bias current (10 pA). | Suitable for lower-bandwidth video or communications where input rail-to-rail is not required. | Choose when 200-MHz bandwidth suffices and cost sensitivity favors a smaller footprint (SOT-23-5, no enable pin). |
Compared with OPA357AIDDARG3, OPA354AIDDARG3 removes shutdown overhead for maximum signal fidelity in static systems, while OPA355AIDBVR trades bandwidth and input range for reduced pin count and cost in less demanding applications.

FAQ
What is the operating supply voltage range for the OPA357AIDDARG3?
The OPA357AIDDARG3 operates from a single supply of 2.5 V to 5.5 V, supporting both 3.3-V and 5-V systems. It functions reliably across this range with specified performance including 250-MHz bandwidth and 150-V/µs slew rate. The OPA357AIDDARG3 maintains rail-to-rail input/output operation and thermal shutdown functionality across the full voltage range.
Does the OPA357AIDDARG3 support rail-to-rail input and output simultaneously?
Yes, the OPA357AIDDARG3 supports true rail-to-rail input and output operation. Its complementary input stage allows common-mode voltage from V− − 0.1 V to V+ + 0.1 V, and its Class AB output stage delivers swing within 100 mV of both rails into 1-kΩ loads. This dual rail-to-rail capability is fully characterized and guaranteed across the −40°C to +125°C temperature range for the OPA357AIDDARG3.
How does the enable function work on the OPA357AIDDARG3?
The OPA357AIDDARG3 enable pin (Pin 5) uses a Schmitt-trigger input with TTL-compatible thresholds: below 0.8 V disables the amplifier (IQ < 6 µA), above 2.0 V enables it (IQ = 4.9 mA). Turn-on time is 100 ns and turn-off is 30 ns. The OPA357AIDDARG3 output enters high-impedance state when disabled, making it suitable for multiplexed signal paths and battery-powered gated operation.
What video performance metrics are guaranteed for the OPA357AIDDARG3?
The OPA357AIDDARG3 guarantees 0.02% differential gain error and 0.09° differential phase error under NTSC conditions with 150-Ω load, meeting broadcast-quality video standards. Its 40-MHz 0.1-dB gain flatness and 250-MHz small-signal bandwidth ensure minimal distortion and timing skew in RGB, Y/C, or composite video line driving applications using the OPA357AIDDARG3.
Is thermal shutdown protection integrated into the OPA357AIDDARG3?
Yes, the OPA357AIDDARG3 includes an on-chip thermal shutdown circuit that activates at 160°C junction temperature and resets automatically when the die cools to 140°C. This protection is fully functional across the rated supply range and load conditions, safeguarding the OPA357AIDDARG3 during sustained overload, short-circuit events, or inadequate PCB thermal design.
