Product details
Overview
OPA607IDBVR 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 handheld test equipment and ultrasonic flow meters.
For engineers reviewing the OPA607IDBVR datasheet, OPA607IDBVR pinout, OPA607IDBVR application, or OPA607IDBVR 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/SOT23-5 package compatibility - all critical for sensor interface designs requiring low-noise, wide dynamic range, and supply voltage flexibility.
Technical Context
The OPA607IDBVR employs a decompensated CMOS architecture with internal phase compensation tailored for stable operation only at gains ≥6 V/V, enabling high GBW (50 MHz) and fast slew rate (24 V/µs) without sacrificing quiescent current efficiency. Its high-impedance CMOS inputs (±10 pA max IB) and rail-to-rail output stage support direct interfacing with high-Z sources like piezoelectric transducers and photodiodes.
Power-down functionality is implemented via a dedicated PD pin (pin 5 in SC70-6, not present in SOT23-5), allowing <1 µA shutdown current while retaining full specification compliance over –40°C to +125°C. The device's 1.5 µV/°C max input offset drift and 120 µV typical VOS ensure stable DC accuracy across industrial temperature ranges.
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, suitable for high-speed signal conditioning in sonar and flow meter front-ends. |
| Quiescent Current | 900 µA (typ) - supports >100-hour battery life in portable test gear when paired with 3.3-V supply and moderate duty cycle. |
| Input Voltage Noise | 3.8 nV/√Hz - ensures sub-µV RMS noise in 10-kHz bandwidth, critical for low-level current-sensing and PM2.5 particle sensor signal integrity. |
| Rail-to-Rail Output | Swings to within 8 mV of VS+ and VS− - maximizes ADC utilization in 2.2–5.5 V systems, preserving >99% of full-scale dynamic range. |
| Input Offset Drift | 1.5 µV/°C (max) - limits total VOS shift to <225 µV over –40°C to +125°C, enabling single-point calibration in industrial safety guards. |
| Supply Voltage Range | 2.2 V to 5.5 V - supports direct integration with Li-ion (3.0–4.2 V), USB (5 V), and low-voltage microcontrollers without LDO overhead. |
| Power-Down Current | 1 µA (max) - reduces system standby power by >99.9% versus active mode, essential for wake-on-event sensor nodes. |
Pinout & Package
OPA607IDBVR is packaged in a 5-pin SOT-23 (DBV) footprint measuring 2.90 mm × 1.60 mm, optimized for space-constrained PCB layouts in handheld tools and optical modules. Unlike the SC70-6 variant, this version omits the dedicated Power-Down (PD) pin and integrates enable logic internally - simplifying routing but requiring external circuitry for shutdown control if needed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+ | Non-inverting input | High-impedance CMOS node (ZIN > 1012 Ω); accepts signals down to VS− rail, ideal for single-supply sensor biasing. |
| IN− | Inverting input | Differential input node; used with feedback network to set gain and common-mode rejection in transimpedance configurations. |
| OUT | Amplifier output | Rail-to-rail stage capable of sourcing/sinking ±20 mA; drives 10-kΩ loads with <0.1% settling error in 1 µs. |
| VS− | Negative supply / ground | Reference for single-supply operation; must be connected directly to PCB ground plane to minimize noise coupling. |
| VS+ | Positive supply | Accepts 2.2–5.5 V; decoupling capacitor (0.1 µF ceramic) required within 2 mm for stable high-frequency performance. |
Key Features
| Feature | Design Value |
|---|---|
| Decompensated stability | Guaranteed stable only at G ≥ 6 V/V - trades gain flexibility for 50-MHz GBW and 24 V/µs slew rate in fixed-gain sensor interfaces. |
| Low-input-bias-current CMOS input | ≤10 pA max IB - prevents signal corruption from leakage in high-impedance photodiode or piezoelectric transducer circuits. |
| Rail-to-rail output swing | Within 8 mV of both rails - eliminates headroom loss in 3.3-V ADC systems, increasing effective resolution by ≥½ LSB. |
| Wide supply range | 2.2 V to 5.5 V operation - enables direct connection to MCU I/O rails or battery inputs without level-shifting or regulation. |
| Industrial temperature grade | Specified from –40°C to +125°C - supports deployment in garden tools, light curtains, and automotive-adjacent industrial sensors. |

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 V/V), 50-MHz GBW, 4.5 nV/√Hz noise, 1.75-mA IQ | Supports variable-gain instrumentation topologies; higher power disqualifies it for ultra-low-power battery use. | Select when gain flexibility or unity-gain buffering is required; avoid where quiescent current budget is <1 mA. |
| OPA837IDBVR | Bipolar input, 50-MHz GBW, 4.7 nV/√Hz noise, 600-µA IQ, G ≥ 1 V/V stable | Higher input bias current (±200 pA) limits use with >1-MΩ source impedances; better DC precision than OPA607IDBVR. | Prefer for DC-critical, low-drift applications with moderate source impedance; not suitable for photodiode or piezo interfaces. |
Compared with OPA365AIDBVR and OPA837IDBVR, the OPA607IDBVR uniquely balances 50-MHz bandwidth, 3.8-nV/√Hz noise, and sub-1-mA quiescent current - making it the only option among the three that meets simultaneous requirements for high-speed, low-noise, and battery longevity in portable sensor systems.

FAQ
What is the minimum stable gain for OPA607IDBVR?
The OPA607IDBVR is decompensated and requires a minimum closed-loop gain of 6 V/V for stable operation. Attempting unity-gain or G = 2 V/V configurations will cause peaking, oscillation, or excessive overshoot. This design choice enables its 50-MHz GBW and 24 V/µs slew rate while maintaining 900 µA quiescent current - a trade-off optimized for fixed-gain sensor signal chains rather than general-purpose use. Always verify stability with actual layout parasitics using TI's TINA-TI simulation models.
Does OPA607IDBVR support true rail-to-rail input?
No, the OPA607IDBVR features rail-to-rail *output* (RRO) but not rail-to-rail *input*. Its input common-mode voltage range extends to the negative rail (VS−), but only up to (VS+) – 1.1 V - meaning it cannot accept signals within 1.1 V of the positive supply. This limitation is acceptable in most single-supply current-sensing and transimpedance applications where the input is referenced near ground or mid-supply, but precludes direct high-side sensing at full VS+ potential without level-shifting.
What package does OPA607IDBVR use, and how does it differ from other OPA607 variants?
OPA607IDBVR uses the 5-pin SOT-23 (DBV) package (2.90 mm × 1.60 mm). Unlike the SC70-6 (DCK) variant, it lacks a dedicated Power-Down (PD) pin - meaning shutdown functionality is not available on this specific part number. Engineers selecting OPA607IDBVR must implement external enable/disable control if low-power sleep modes are required, whereas the SC70-6 version supports hardware-controlled power-down via pin 5.
Can OPA607IDBVR drive capacitive loads, and what is the recommended isolation resistor?
Yes, the OPA607IDBVR can drive capacitive loads up to 100 pF with proper compensation. For a 50-pF load, TI recommends an isolation resistor (RISO) of ~40 Ω in series with the output to maintain ≥45° phase margin. Larger loads require proportionally higher RISO; for example, 100 pF needs ~80 Ω. This technique preserves stability without degrading small-signal bandwidth significantly - critical in ultrasonic flow meter timing circuits where transient response must remain under 1 µs.
How does the input offset voltage drift of OPA607IDBVR impact long-term measurement accuracy?
The OPA607IDBVR has a maximum input offset drift of 1.5 µV/°C over –40°C to +125°C. Over this full range, total drift is bounded at ±225 µV - which, combined with its 120 µV typical VOS, yields a worst-case total offset of ±345 µV. In a 5-V, 12-bit system (1.22 mV/LSB), this represents <0.3 LSB error - sufficient for most industrial current-sensing and PM2.5 sensor applications without per-unit calibration, though high-precision metrology may require trimming.
