Product details
Overview
OPA2607IDR from Texas Instruments is a dual-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, ultrasonic flow meters, and handheld test equipment requiring precision, low quiescent current (900 µA per channel), and stable operation at minimum gain ≥6 V/V.
For engineers reviewing the OPA2607IDR datasheet, OPA2607IDR pinout, OPA2607IDR application, or OPA2607IDR equivalent, this page provides verified technical context, package-specific pin functions, real-world use cases in sensor signal conditioning and transimpedance amplification, and validated alternative options for design flexibility and supply continuity.
Technical Context
The OPA2607IDR employs a decompensated CMOS architecture requiring minimum closed-loop gain of 6 V/V for stability, enabling high bandwidth (50 MHz) with low power consumption (900 µA/channel). Its rail-to-rail output stage supports full-scale ADC interfacing in low-voltage systems (2.2–5.5 V), while its 10 pA max input bias current and 1.5 µV/°C max offset drift ensure accuracy in high-impedance sensor interfaces like piezoelectric transducers and photodiodes.
Each channel features independent Power Down (PD1/PD2) control, reducing quiescent current to ≤1 µA per amplifier when disabled. The device is fully specified across –40°C to +125°C and includes robust ESD protection (±2000 V HBM), making it suitable for industrial and portable battery-powered environments where thermal resilience and power-state agility are critical.
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, supporting fast signal conditioning in ultrasonic and current-sensing applications. |
| Quiescent Current (per channel) | 900 µA (typical) - Allows dual-channel amplification in space-constrained, battery-operated devices without compromising bandwidth. |
| Input Voltage Noise Density | 3.8 nV/√Hz - Low-noise performance critical for amplifying weak signals from PM2.5 sensors, photodiodes, and piezoelectric transducers. |
| Rail-to-Rail Output Swing | Within 8 mV of supply rails - Maximizes dynamic range into 12–16-bit ADCs in single-supply systems (e.g., 3.3 V or 5 V). |
| Input Offset Drift (max) | 1.5 µV/°C - Ensures stable DC accuracy over industrial temperature range (–40°C to +125°C) in precision current sensing. |
| Minimum Stable Gain | 6 V/V - Requires external gain-setting network; prevents instability in high-speed configurations but mandates careful layout for capacitive loads. |
| Power Down Current (per channel) | 1 µA (max) - Enables rapid channel disablement in multi-stage signal chains to extend battery life in handheld test gear. |
Pinout & Package
OPA2607IDR is supplied in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm, rated for surface-mount assembly and industrial temperature operation (–40°C to +125°C).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of Channel 1 - Rail-to-rail capable; drives ADC inputs or downstream buffers with minimal headroom loss. |
| 2 | IN1− | Inverting input of Channel 1 - High-impedance CMOS node; accepts feedback networks for transimpedance or difference amplification. |
| 3 | IN1+ | Noninverting input of Channel 1 - Used for reference-biased sensing (e.g., current-shunt monitoring) or unity-gain buffer configurations. |
| 4 | VS− | Negative supply / ground - Serves as common return for both channels; must be low-impedance to minimize PSRR degradation. |
| 5 | VS+ | Positive supply - Accepts 2.2–5.5 V; powers both amplifiers and internal bias circuitry; decoupling required near pin. |
| 6 | IN2− | Inverting input of Channel 2 - Electrically isolated from Channel 1; enables dual-path signal processing (e.g., differential sensor pairs). |
| 7 | OUT2 | Output of Channel 2 - Independent output; supports simultaneous dual-channel acquisition in optical modules or safety guards. |
| 8 | IN2+ | Noninverting input of Channel 2 - Matches IN1+ functionality; allows matched gain/offset paths for ratiometric or chopper-stabilized topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Decompensated architecture | Enables 50-MHz GBW at only 900 µA/channel - achieves high-speed performance without the power penalty of fully compensated op amps. |
| Rail-to-rail output (RRO) | Swings to within 8 mV of VS+ and VS− - preserves >99% of ADC full-scale range in 3.3-V systems, improving SNR and resolution utilization. |
| Independent Power Down pins (PD1/PD2) | Each channel disables separately with ≤1 µA quiescent draw - supports dynamic power gating in multi-function instruments like garden tool controllers. |
| Low input bias current (≤10 pA) | Maintains accuracy with high-Z sources (e.g., pH electrodes, photodiodes) without significant error from leakage-induced offset shift. |
| Wide supply range (2.2 V to 5.5 V) | Operates from single Li-ion cell (3.0–4.2 V) or regulated 3.3 V/5 V rails - eliminates need for level-shifting in mixed-voltage subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, rail-to-rail output op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2365AIDR | Lower GBW (50 MHz same), higher quiescent current (1.6 mA/channel), no Power Down mode, lower input bias current (0.2 pA). | Better for ultra-high-Z sensor buffering where power-down is unnecessary; less suitable for battery-critical designs. | Select when lowest possible input bias current outweighs power-down capability and quiescent current budget. |
| LMV797MMX/NOPB | Lower GBW (88 MHz), higher noise (6.5 nV/√Hz), no Power Down, wider supply range (2.7–5.5 V), higher IB (0.1 pA). | Preferred for higher-speed, non-battery applications where noise floor is less critical than bandwidth margin. | Choose when >50-MHz small-signal bandwidth is required and system supply is guaranteed ≥2.7 V. |
Compared with OPA2607IDR, OPA2365AIDR offers superior input bias performance but lacks power management; LMV797MMX/NOPB trades noise and power efficiency for raw bandwidth-making OPA2607IDR the optimal balance for portable, precision, dual-channel analog front-ends.

FAQ
What is the minimum stable gain for OPA2607IDR?
The OPA2607IDR is decompensated and requires a minimum closed-loop gain of 6 V/V for stability. This architectural choice enables its 50-MHz gain-bandwidth product while maintaining low quiescent current. Using gains below 6 V/V may cause peaking or oscillation; TI recommends verifying phase margin with capacitive load simulations when designing with OPA2607IDR.
Does OPA2607IDR support single-supply operation?
Yes, OPA2607IDR 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 3.3-V or 5-V microcontrollers and ADCs without level-shifting circuitry-critical for compact, low-cost designs using OPA2607IDR.
How does the Power Down feature work on OPA2607IDR?
OPA2607IDR has two independent Power Down pins (PD1 and PD2), one per channel. Driving PDx low disables the corresponding amplifier, reducing its quiescent current to ≤1 µA. The pin is CMOS-compatible with logic thresholds at 0.2×VS (low) and 0.7×VS (high). Floating the PD pin enables the amplifier-no external pull-up is required. This feature is actively used in OPA2607IDR-based handheld tools to gate unused signal paths dynamically.
What is the input offset voltage specification for OPA2607IDR?
The OPA2607IDR has a typical input offset voltage of 120 µV, with a maximum of ±600 µV over temperature (–40°C to +125°C). Its input offset drift is specified at ±1.5 µV/°C maximum, ensuring predictable DC error accumulation across industrial temperature ranges. These values are production-tested and documented in the SBOS981J datasheet-key for precision current-sensing applications relying on OPA2607IDR.
Can OPA2607IDR drive capacitive loads directly?
OPA2607IDR can drive moderate capacitive loads (≤100 pF) without external isolation, but stability depends on gain and supply voltage. At G = 6 V/V and VS = 5.5 V, phase margin remains >45° up to ~50 pF; beyond that, a series isolation resistor (e.g., 10–50 Ω) is recommended. TI's Figure 7-18 in the OPA2607IDR datasheet provides exact RISO vs CLOAD guidance-essential for reliable transimpedance amplifier layouts using OPA2607IDR.
