Product details
Overview
OPA727AIDGKRG4 from Texas Instruments is a single-channel, e-trim™ high-precision CMOS operational amplifier in an 8-pin VSSOP package. It delivers 20MHz gain-bandwidth, 30V/µs slew rate, 150µV max input offset voltage, 1.5µV/°C max offset drift, and rail-to-rail output swing within 150mV of supply rails - enabling high-fidelity signal conditioning in optical transimpedance amplifiers and precision ADC drivers.
For engineers reviewing the OPA727AIDGKRG4 datasheet, OPA727AIDGKRG4 pinout, OPA727AIDGKRG4 application, or OPA727AIDGKRG4 equivalent, key selection criteria include its low 500pA max input bias current for photodiode interfaces, 6nV/√Hz noise at 100kHz for clean small-signal amplification, and guaranteed operation from –40°C to +125°C in industrial and test equipment designs.
Technical Context
The OPA727AIDGKRG4 employs e-trim™ technology - digital trimming performed post-packaging - to stabilize offset voltage and temperature drift against mechanical stress-induced parameter shifts. Its CMOS input stage enables ultra-low bias current (±500pA max) and high input impedance (10¹¹ Ω || 5pF), critical for high-impedance sensor interfaces.
This device features a Class AB rail-to-rail output stage capable of driving ≥100kΩ loads to within 150mV of V+ and V– while maintaining >110dB open-loop gain. It is unity-gain stable, supports single-supply operation from 4V to 12V, and includes ESD-protected inputs with diode clamping to rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 20MHz - enables stable closed-loop operation up to 100kHz with G = 200, suitable for anti-aliasing filters and wideband sensor signal chains. |
| Input Offset Voltage (max) | 150µV - ensures ≤0.003% full-scale error in ±2.5V-range 16-bit ADC driver applications (e.g., ADS8342). |
| Offset Drift (max) | 1.5µV/°C - limits thermal-induced error to <18µV over 0°C to 125°C ambient, critical for uncalibrated industrial instrumentation. |
| Slew Rate | 30V/µs - supports 5V step settling in ≤450ns at 0.01%, meeting timing requirements for 250kSPS SAR ADC acquisition windows. |
| Input Bias Current (max) | 500pA - allows use with photodiodes having >100MΩ shunt resistance without significant DC error in transimpedance configurations. |
| Output Swing (vs rail) | 150mV - provides >4.7Vpp dynamic range on +5V supply, maximizing SNR in single-supply audio and process control front-ends. |
| Quiescent Current | 4.3mA - balances performance and power in battery-operated portable test gear and handheld analyzers. |
Pinout & Package
VSSOP-8 (DGK) package with exposed thermal pad on underside; requires connection of thermal pad to V– for optimal thermal performance and reliability.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - must be left floating or grounded per layout guidelines; not usable as shield or bias node. |
| 2 | V+ | Positive supply rail - bypass with 1nF ceramic + 1µF tantalum to minimize PSRR degradation at high frequencies. |
| 3 | OUT | Amplifier output - capable of sourcing/sinking ≥40mA; rail-to-rail swing enables direct interfacing with ADC inputs without level-shifting. |
| 4 | NC | No internal connection - electrically isolated; PCB trace should avoid routing signals beneath this pin. |
| 5 | NC | No internal connection - same isolation requirement as Pin 1 and Pin 4; no thermal or electrical function. |
| 6 | IN– | Inverting input - high-impedance CMOS node; sensitive to leakage; guard ring recommended in photodiode applications. |
| 7 | IN+ | Non-inverting input - matched to IN– for common-mode rejection; accepts input down to V– (true single-supply operation). |
| 8 | V– | Negative supply rail - thermal die pad must be soldered to V– plane for thermal management and mechanical reliability. |
Key Features
| Feature | Design Value |
|---|---|
| e-trim™ post-package trimming | Digitally corrects offset and drift after molding, eliminating stress-induced parametric shift - ensures 150µV/1.5µV/°C specs hold across full temperature range. |
| Rail-to-rail output stage | Swings to within 150mV of V+ and V– under light load (≥100kΩ), preserving >94% of supply voltage as usable dynamic range on +5V systems. |
| Ultra-low input bias current | ≤500pA max enables accurate I/V conversion for photodiodes with capacitance <10pF and shunt resistance >1GΩ without significant DC error. |
| High CMRR & PSRR | 94dB CMRR and 150µV/V PSRR minimize errors from ground bounce and supply ripple in mixed-signal PCB layouts. |
| Unity-gain stability | Stable with gain ≥1 and capacitive loads ≤20pF - eliminates need for external compensation in most buffer and gain-stage applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2727AIDRBRG4 | Dual-channel version in DFN-8; identical offset (150µV max), drift (1.5µV/°C), and bandwidth (20MHz), but shares supply current budget across two amps (4.3mA/ch). | Used where space-constrained dual-channel signal paths exist (e.g., differential sensor pairs), not single-ended front-ends. | Select OPA2727AIDRBRG4 only when dual-channel integration reduces board area or interconnect complexity without compromising per-channel performance. |
| OPA727AIDGKR | Same VSSOP-8 package and electrical specs, but lacks G4 suffix - indicates non-lead-free finish (Pb/Sn); RoHS compliance differs. | Restricted to legacy industrial systems where Pb-free assembly is not mandated; incompatible with modern lead-free reflow profiles. | Choose OPA727AIDGKR only for backward compatibility in existing Pb-based manufacturing lines; OPA727AIDGKRG4 is preferred for new designs. |
Compared with OPA2727AIDRBRG4, the OPA727AIDGKRG4 offers dedicated single-channel optimization for critical signal paths, while versus OPA727AIDGKR, it ensures full RoHS compliance and compatibility with standard lead-free reflow processes without performance trade-offs.

FAQ
What is the maximum operating temperature range for the OPA727AIDGKRG4?
The OPA727AIDGKRG4 is fully specified and tested from –40°C to +125°C. This extended temperature range is validated per the SBOS314H datasheet and supports deployment in automotive engine compartments, industrial motor drives, and outdoor telecom equipment where ambient extremes occur.
Does the OPA727AIDGKRG4 support single-supply operation?
Yes, the OPA727AIDGKRG4 supports true single-supply operation from 4V to 12V. Its input common-mode range extends to V–, and output swings to within 150mV of both rails - enabling direct interfacing with microcontrollers and ADCs powered from +5V or +12V without level-shifting circuitry.
What package type is used for the OPA727AIDGKRG4?
The OPA727AIDGKRG4 uses the VSSOP-8 (DGK) package - an 8-pin, 3mm × 3mm surface-mount package with gull-wing leads and an exposed thermal pad on the underside. The pad must be soldered to the V– plane for thermal and mechanical reliability.
Is the OPA727AIDGKRG4 pin-compatible with other members of the OPA727 family?
Yes, all OPA727 variants in VSSOP-8 (including OPA727AIDGKR and OPA727AIDGKRG4) share identical pinout and footprint. The G4 suffix denotes lead-free finish and RoHS compliance but does not affect electrical or mechanical compatibility.
What is the typical quiescent current of the OPA727AIDGKRG4?
The OPA727AIDGKRG4 draws 4.3mA typical quiescent current per amplifier at +25°C and ±5V supply. This value increases to ≤6.5mA over temperature (–40°C to +125°C), making it suitable for portable test equipment where power efficiency and precision are both required.
