Product details
Overview
OPA2652E/250G4 from Texas Instruments is a dual, wideband voltage-feedback operational amplifier in SOT23-8 package, delivering 700MHz unity-gain bandwidth, 335V/µs slew rate, and ±140mA output current per channel at ±5V supply. It serves as a differential ADC driver (e.g., for ADS807), video line driver, and active filter building block in high-speed signal conditioning.
For engineers reviewing the OPA2652E/250G4 datasheet, OPA2652E/250G4 pinout, OPA2652E/250G4 application, or OPA2652E/250G4 equivalent, key selection criteria include its 700MHz G=+1 bandwidth, ±1.5mV input offset voltage, 0.05%/0.03° differential gain/phase error, and SOT23-8 thermal resistance of 150°C/W - all critical for precision high-frequency analog front-ends.
Technical Context
The OPA2652E/250G4 uses classical voltage-feedback architecture with fully differential, symmetrical inputs optimized for low DC error and high AC fidelity. Its internal unity-gain compensation enables stable operation at G=+1 while achieving 700MHz small-signal bandwidth and 50MHz 0.1dB flatness.
It supports bipolar (±3V to ±6V) and single-supply (6V–12V) operation, with 5.5mA/channel quiescent current and 200MHz gain-bandwidth product. The device maintains 66dB SFDR at 5MHz and exhibits 8nV/√Hz input voltage noise above 1MHz - enabling clean signal amplification in ADC driver and composite video paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-Signal Bandwidth (G=+1) | 700MHz - enables direct buffering of >300MHz baseband signals without gain-induced bandwidth loss |
| Slew Rate | 335V/µs - supports full-scale 4Vpp transitions in ≤12ns, critical for fast-pulse and video applications |
| Input Offset Voltage | ±1.5mV max - ensures <0.03% gain error in 50Ω-driven differential ADC interfaces |
| Differential Gain/Phase Error | 0.05%/0.03° - meets NTSC studio-grade video linearity requirements into 150Ω load |
| Output Current (sourcing/sinking) | ±140mA - drives 50Ω loads to ±2.5V while maintaining linearity and thermal safety |
| Supply Voltage Range | ±3V to ±6V - compatible with standard analog rails and supports single-supply operation down to +6V |
| Quiescent Current (total) | 11mA min / 15.5mA max - balances low-power operation with high-speed performance across temperature |
Pinout & Package
SOT23-8 package with exposed pad (DCN designation); 1.6mm × 2.9mm footprint, 1.1mm height, thermal resistance θJA = 150°C/W. Pin 1 marked via laser etch "C52".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (+In A) | Noninverting input, Channel A | High-impedance differential input node; requires bias current cancellation resistor (e.g., 205Ω to ground) for DC accuracy |
| 2 (–In A) | Inverting input, Channel A | Feedback node; connects to RF/RG network; parasitic capacitance here directly impacts stability |
| 3 (Out A) | Output, Channel A | Capable of ±140mA drive; requires series isolation resistor (e.g., 5–20Ω) when driving >2pF capacitive loads |
| 4 (–VS) | Negative supply rail | Must be decoupled to ground with 0.1µF ceramic capacitor; 0.1µF cap between +VS and –VS improves 2nd-harmonic distortion |
| 5 (+VS) | Positive supply rail | Same decoupling requirements as –VS; 0.1µF cap between rails reduces power-supply coupling artifacts |
| 6 (–In B) | Inverting input, Channel B | Independent second channel input; identical electrical characteristics and layout rules as Channel A |
| 7 (+In B) | Noninverting input, Channel B | Matches Channel A input structure; allows independent dual-channel configuration or cascaded pulse delay |
| 8 (Out B) | Output, Channel B | Electrically isolated from Out A; crosstalk <–100dBc at 5MHz enables simultaneous high-fidelity signal paths |
Key Features
| Feature | Design Value |
|---|---|
| Unity-gain stable voltage feedback | Enables robust G=+1 buffer operation with 0dB peaking - eliminates need for external compensation in most ADC driver layouts |
| Low dG/dφ (0.05%/0.03°) | Preserves color fidelity and timing integrity in NTSC/PAL video transmission without post-correction circuitry |
| High output current (±140mA) | Drives 50Ω coaxial cables and parallel ADC inputs directly, avoiding external buffers in compact designs |
| Ultra-small SOT23-8 package | Reduces PCB area by >60% vs SO-8; enables dense mixed-signal layouts where space and thermal mass are constrained |
| Low input voltage noise (8nV/√Hz) | Maintains SNR >68dB in 10MHz bandwidth applications - critical for 12-bit+ data acquisition front-ends |
Applications
| Differential ADC Driver | Consumer Video Line Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2650 | Lower 500MHz G=+1 bandwidth; same SOT23-8 package and ±140mA drive | Reduced large-signal bandwidth (35MHz vs 50MHz) limits use in >40Msps ADC drivers | Select OPA2650 only when 700MHz bandwidth is unnecessary and cost reduction is primary |
| AD8056 | Higher 300mA output current but higher 6.5mA/channel quiescent current; SO-8 only | Larger SO-8 footprint and no SOT23-8 option increases board area and thermal resistance | Choose AD8056 only when >±140mA drive is required and space constraints allow SO-8 |
Compared with OPA2652E/250G4, OPA2650 trades 200MHz bandwidth for lower cost in space-constrained designs, while AD8056 provides higher output current at the expense of quiescent power and package size - making OPA2652E/250G4 optimal for balanced high-speed, low-area, low-power applications.

FAQ
What is the maximum safe operating voltage for OPA2652E/250G4?
The OPA2652E/250G4 has an absolute maximum supply voltage rating of ±6.5V. Its specified operating range is ±3V to ±6V, with recommended operation at ±5V for optimal AC performance and thermal margin. Exceeding ±6.5V risks permanent damage per TI's Absolute Maximum Ratings table in SBOS125A.
Does OPA2652E/250G4 require external compensation for unity-gain stability?
No, the OPA2652E/250G4 is internally compensated for unity-gain stability. Its 700MHz G=+1 bandwidth and 0dB typical peaking (per Figure 1) confirm stable operation without external components - a key design advantage over many wideband op amps requiring careful compensation network tuning.
Can OPA2652E/250G4 drive a 50Ω load directly?
Yes, OPA2652E/250G4 can drive a 50Ω load directly: its ±140mA output current supports ±2.5V swing into 50Ω (per Electrical Characteristics table). However, a 5–10Ω series isolation resistor is recommended near the output pin to maintain stability when PCB trace capacitance exceeds 2pF.
What is the thermal resistance (θJA) of OPA2652E/250G4 in its SOT23-8 package?
The OPA2652E/250G4 in SOT23-8 (DCN) package has a junction-to-ambient thermal resistance (θJA) of 150°C/W, as specified in the Thermal Characteristics table. This value assumes standard JEDEC 2-layer board conditions; actual θJA improves with added copper pour and thermal vias under the exposed pad.
How does OPA2652E/250G4 achieve low differential gain/phase error in video applications?
OPA2652E/250G4 achieves 0.05%/0.03° dG/dφ through precision-trimmed input stage symmetry, ultra-low input bias current drift (<7µA/°C), and optimized internal compensation that minimizes group delay variation across 4.43MHz NTSC luminance/chroma bands - verified in TI's Composite Video dG/dφ test (Figure 14).
