Product details
Overview
OPA607IDCKT from Texas Instruments is a single-channel, decompensated CMOS operational amplifier optimized for cost-sensitive, low-power, high-bandwidth applications. It delivers 50-MHz gain-bandwidth product, 3.8 nV/√Hz input voltage noise, rail-to-rail output swing within 8 mV of supply rails, and operates from 2.2 V to 5.5 V - enabling precision current sensing and transimpedance amplification in battery-powered ultrasonic flow meters and PM2.5 sensors.
For engineers reviewing the OPA607IDCKT datasheet, OPA607IDCKT pinout, OPA607IDCKT application, or OPA607IDCKT equivalent, key selection criteria include its minimum stable gain of 6 V/V, 900 µA quiescent current, power-down mode (≤1 µA), ±10 pA max input bias current, and SC70-6 package compatibility with space-constrained sensor front-ends.
Technical Context
The OPA607IDCKT uses a decompensated CMOS architecture requiring ≥6 V/V closed-loop gain for stability, enabling high-speed performance without sacrificing low-noise (3.8 nV/√Hz) or low-quiescent-current (900 µA) operation. Its rail-to-rail output supports full-scale ADC utilization in low-voltage systems down to 2.2 V.
Input stage features high-impedance CMOS inputs (≤10 pA IB) and phase-reversal protection, making it suitable for interfacing with high-impedance sources like piezoelectric transducers and photodiodes. Power-down mode reduces current to ≤1 µA via dedicated PD pin, supporting portable equipment duty cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 50 MHz - enables stable closed-loop operation up to ~8 MHz at G = 6 V/V for fast signal conditioning in sonar and flow metering. |
| Quiescent Current | 900 µA (typ) - supports >1-year battery life in handheld test equipment and optical modules with intermittent operation. |
| Input Voltage Noise | 3.8 nV/√Hz - preserves SNR in low-level current-sensing and transimpedance stages for PM sensor analog front-ends. |
| Output Swing | Within 8 mV of rails - maximizes dynamic range into 12–16-bit ADCs in single-supply 2.2–5.5 V systems. |
| Power-Down Current | ≤1 µA - allows deep sleep between measurement cycles in garden tools and safety light curtains. |
| Input Offset Drift | ±1.5 µV/°C (max) - ensures <1.2 µV total drift over –40°C to +125°C, critical for industrial temperature-stable sensing. |
| Supply Range | 2.2 V to 5.5 V - supports direct Li-ion (3.0–4.2 V) and coin-cell (3 V) operation without LDO overhead. |
Pinout & Package
OPA607IDCKT is packaged in a 6-pin SC70 (DCK) case measuring 2.00 mm × 1.25 mm, optimized for high-density PCB layouts in portable instrumentation and compact sensor modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+ | Noninverting input | High-impedance CMOS node (≤10 pA IB); accepts signals down to VS– rail for single-supply sensor interfaces. |
| IN− | Inverting input | Differential input node with phase-reversal protection; used in transimpedance and difference amplifier configurations. |
| OUT | Amplifier output | Rail-to-rail capable (8 mV from rails); drives 10 kΩ loads with 24 V/µs slew rate and <1 µs settling to 0.1%. |
| VS+ | Positive supply | Accepts 2.2–5.5 V; powers internal bias circuitry and output stage; must be decoupled with 100 nF near pin. |
| VS− | Negative supply / ground | Reference for single-supply operation; common return for input and output; connects to system ground or negative rail. |
| PD | Power-down control | Logic-compatible input: low (≤0.2×VS) disables amplifier (≤1 µA IQ); high or floating enables operation. |
Key Features
| Feature | Design Value |
|---|---|
| Decompensated stability | Guaranteed stable only at ≥6 V/V gain - prevents oscillation in high-speed TIA designs while enabling 50-MHz GBW. |
| Rail-to-rail output | Swings to within 8 mV of VS+ and VS− - preserves >99% of ADC full-scale range in 3.3 V and lower systems. |
| Low-input-bias-current CMOS | ≤10 pA max IB - avoids signal corruption when amplifying high-impedance sources (e.g., photodiodes, piezo elements). |
| Integrated power-down | Single-pin enable/disable with ≤1 µA shutdown current - eliminates need for external load switches in portable devices. |
| Wide temperature range | Specified from –40°C to +125°C - supports deployment in automotive cabin sensors, industrial motor controls, and outdoor tools. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA365AIDBVR | Unity-gain stable (G ≥ 1), 50-MHz GBW, 4.5 nV/√Hz noise, 1.6 mA IQ - higher power, no power-down pin. | Better for unity-gain buffer or low-gain signal routing; unsuitable where power-down or ≥6 V/V gain is required. | Select OPA365AIDBVR only if unity-gain stability is mandatory and power budget allows +78% IQ increase. |
| OPA837IDBVR | Bipolar input, 50-MHz GBW, 4.7 nV/√Hz, 0.6 mA IQ, unity-gain stable - higher input bias current (±200 nA), no PD pin. | Preferred for low-noise DC-coupled applications with moderate source impedance; not for high-Z sensors. | Choose OPA837IDBVR when interfacing with resistive or low-impedance sources and unity-gain operation is needed. |
Compared with OPA607IDCKT, OPA365AIDBVR offers unity-gain stability at higher quiescent current and no power-down capability, while OPA837IDBVR trades CMOS input advantages for bipolar noise-performance tradeoffs - making OPA607IDCKT uniquely suited for low-power, high-Z, gain ≥6 sensor amplification.

FAQ
What is the minimum stable gain for OPA607IDCKT?
The OPA607IDCKT is decompensated and requires a minimum closed-loop gain of 6 V/V for stability. Attempting unity-gain or gains below 6 V/V may cause oscillation or excessive ringing. This design enables its 50-MHz GBW while maintaining low quiescent current. Always verify phase margin using simulation or bench testing when implementing OPA607IDCKT in non-inverting or inverting configurations at G = 6 V/V or higher.
Does OPA607IDCKT support true rail-to-rail input?
No, OPA607IDCKT does not feature rail-to-rail input. Its input common-mode voltage range extends to the negative rail (VS−) but only to (VS+) – 1.1 V. However, its rail-to-rail output swings within 8 mV of both supply rails, maximizing dynamic range for ADC interfacing. For applications requiring full RRI, consider alternatives like the OPA320 series - but note they lack the OPA607IDCKT's 50-MHz GBW and power-down capability.
How is the power-down pin (PD) used on OPA607IDCKT?
The PD pin on OPA607IDCKT is an active-low control: pulling PD ≤ 0.2 × VS places the amplifier in shutdown mode with ≤1 µA quiescent current; leaving PD floating or tying it to VS+ enables normal operation. No external pull-up is required. The turn-on/turn-off delays are 10–15 µs and ≤0.5 µs respectively, making OPA607IDCKT suitable for burst-mode sensing in PM2.5 detectors and ultrasonic flow meters.
Can OPA607IDCKT operate from a single 3.3-V supply?
Yes, OPA607IDCKT is fully specified for single-supply operation from 2.2 V to 5.5 V, including 3.3 V. At VS = 3.3 V, it maintains 50-MHz GBW, 900 µA IQ, and rail-to-rail output swing (within 8 mV of 0 V and 3.3 V). Input common-mode range spans 0 V to 2.2 V, allowing direct connection to ground-referenced sensors. All electrical characteristics in the datasheet are validated across this supply range.
What package type is used for OPA607IDCKT?
OPA607IDCKT uses the SC70-6 (DCK) package: a 6-pin surface-mount outline measuring 2.00 mm × 1.25 mm with 0.65-mm lead pitch. This compact footprint supports high-density layouts in space-constrained applications such as handheld test gear and optical sensor modules. Thermal resistance is RθJA = 219.7°C/W, requiring careful attention to PCB copper area and thermal vias for sustained high-output-current operation.
