Product details
Overview
OPA607IDBVT 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. It is widely used in current-sensing circuits and ultrasonic flow meters where low quiescent current (900 µA typical) and stable ≥6 V/V gain are critical.
For engineers reviewing the OPA607IDBVT datasheet, OPA607IDBVT pinout, OPA607IDBVT application, or OPA607IDBVT equivalent, this page provides verified technical context, validated pin functions, confirmed package dimensions (SOT-23-5, 2.90 mm × 1.60 mm), real-world application constraints, and two rigorously cross-checked alternative parts with documented functional and application-level differences.
Technical Context
The OPA607IDBVT uses a decompensated CMOS architecture requiring minimum closed-loop gain of 6 V/V for stability, enabling its 50-MHz GBW while maintaining only 900 µA quiescent current. Its high-impedance CMOS inputs (10 pA max bias current) and low 1.5 µV/°C offset drift support precision interfacing with high-output-impedance sensors like piezoelectric transducers.
It integrates a dedicated Power Down (PD) pin that reduces quiescent current to ≤1 µA when pulled low, making it suitable for battery-powered handheld test equipment and portable PM2.5 sensors. The rail-to-rail output achieves 8 mV headroom at both rails across –40°C to +125°C, maximizing ADC dynamic range in low-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 50 MHz - enables stable amplification up to ~8 MHz at G = 6 V/V, supporting fast current-sensing loop response. |
| Quiescent Current | 900 µA typical - allows continuous operation in energy-constrained devices such as garden tools and optical modules. |
| Input Voltage Noise | 3.8 nV/√Hz - ensures minimal signal degradation in low-level sensor interfaces like photodiode transimpedance stages. |
| Rail-to-Rail Output | Swings to within 8 mV of VS+ and VS− - preserves full-scale utilization of 12-bit+ ADCs in 2.2–5.5 V systems. |
| Power Down Current | ≤1 µA - extends battery life in intermittent-use applications including light curtains and safety guards. |
| Input Offset Drift | 1.5 µV/°C max - maintains accuracy over industrial temperature range (–40°C to +125°C) without recalibration. |
| Supply Voltage Range | 2.2 V to 5.5 V - supports direct integration with Li-ion, 3.3 V, and 5 V logic domains without level-shifting. |

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; 50-MHz GBW; 4.5 nV/√Hz noise; no Power Down pin. | Preferred for G = 1–5 applications (e.g., buffer stages); unsuitable where power gating is required. | Select OPA365AIDBVR only if gain < 6 V/V is needed and shutdown functionality is unnecessary. |
| OPA837IDBVR | Bipolar input; 50-MHz GBW; 4.7 nV/√Hz; 105 V/µs slew rate; no Power Down. | Better for high-speed pulse amplification (e.g., TOF lidar), but higher noise and bias current limit sensor interface use. | Choose OPA837IDBVR only when >24 V/µs slew rate is mandatory and CMOS input impedance is not required. |
Compared with OPA365AIDBVR and OPA837IDBVR, the OPA607IDBVT uniquely combines decompensated 50-MHz bandwidth, rail-to-rail output, integrated Power Down, and CMOS input performance-making it the only option among the three qualified for low-power, high-precision, gain ≥6 sensor front-ends operating across –40°C to +125°C.

FAQ
What is the minimum stable gain for OPA607IDBVT?
The OPA607IDBVT is decompensated and requires a minimum closed-loop gain of 6 V/V for stability. This design enables its 50-MHz gain-bandwidth product while maintaining low quiescent current. Attempting to use OPA607IDBVT at gains below 6 V/V may cause oscillation or excessive ringing. For unity-gain or low-gain applications, consider alternatives like OPA365AIDBVR.
Does OPA607IDBVT support single-supply operation?
Yes, OPA607IDBVT supports true single-supply operation from 2.2 V to 5.5 V. Its input common-mode range extends to the negative rail (VS−), and its rail-to-rail output swings within 8 mV of both supply rails. This allows direct interfacing with microcontrollers and ADCs in 3.3 V or battery-powered systems without level-shifting circuitry.
What is the function of the PD pin on OPA607IDBVT?
The PD (Power Down) pin on OPA607IDBVT disables the amplifier core when pulled low (≤0.2 × VS), reducing quiescent current to ≤1 µA. When left floating or tied to VS+, the device operates normally. This pin enables rapid, logic-controlled power gating-critical for extending battery life in handheld test equipment and intermittent-use sensors using OPA607IDBVT.
Can OPA607IDBVT drive capacitive loads?
OPA607IDBVT can drive moderate capacitive loads, but phase margin degrades with increasing capacitance. At 100 pF, phase margin drops to ~45° (per Fig. 7-16). For loads >50 pF, TI recommends adding an isolation resistor (RISO) between the output and load-values range from 10 Ω to 90 Ω depending on load size and gain, as shown in Fig. 7-18. Uncompensated heavy capacitive loading may cause instability in OPA607IDBVT.
Is OPA607IDBVT suitable for photodiode transimpedance applications?
Yes, OPA607IDBVT is well-suited for photodiode transimpedance applications due to its 10 pA max input bias current, 3.8 nV/√Hz input voltage noise, and high 50-MHz GBW. Its CMOS input avoids loading high-impedance photodiodes, and rail-to-rail output maximizes dynamic range. However, stability must be ensured via proper feedback capacitor selection (e.g., 2.5 pF typical) and layout-designs should follow TI's OPA607IDBVT application curves in SBOS981J.
