Product details
Overview
HA5023IBZ from Intersil is a dual current-feedback operational amplifier optimized for high-fidelity video signal conditioning, delivering 125MHz -3dB bandwidth at unity gain, 475V/µs slew rate, and 0.03% differential gain / 0.03° differential phase performance when driving dual 75Ω back-terminated video lines.
For engineers reviewing the HA5023IBZ datasheet, HA5023IBZ pinout, HA5023IBZ application, or HA5023IBZ equivalent, this page provides verified circuit role, package mapping, pin-level design meaning, real-world video system use cases, and validated alternative options with documented functional trade-offs.
Technical Context
The HA5023IBZ implements a high-speed bipolar dielectric-isolation current-feedback architecture with transimpedance gain stage, enabling bandwidth scalability via feedback resistor (RF) selection-e.g., 125MHz at RF = 1kΩ (AV = +1), 95MHz at RF = 681Ω (AV = +2), and 65MHz at RF = 383Ω (AV = +10). Its dual-channel layout maintains channel separation >70dB at 10MHz.
It operates from ±4.5V to ±15V supplies, delivers ±3.0V output swing into 150Ω, supports 15mA continuous output current per channel, and integrates ESD protection rated at 4000V HBM-guaranteed over –40°C to +85°C with ±5V supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (-3dB) | 125MHz at AV = +1, RF = 1kΩ - enables full NTSC/PAL/HD-SDI baseband video passband without attenuation |
| Slew Rate | 475V/µs - supports clean 1080p60 video edge transitions with <1% distortion |
| Differential Gain / Phase | 0.03% / 0.03° - meets broadcast-grade video fidelity requirements for RGB/YUV distribution |
| Input Offset Voltage | 0.8mV typical - minimizes DC error accumulation in multi-stage video gain blocks |
| Supply Current | 7.5mA per amplifier - enables dual-channel operation within 15mA total quiescent budget |
| Output Drive | ±3.0V into 150Ω - directly drives two 75Ω coaxial cables with proper back-termination |
| ESD Rating | 4000V HBM - ensures robustness during board handling and system integration |
Pinout & Package
HA5023IBZ is housed in an 8-lead SOIC package (JEDEC MS-012-AA, pkg drawing M8.15), 3.9mm × 4.9mm body, 1.27mm lead pitch, Pb-free matte tin termination, RoHS compliant, MSL Level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT1 | Amplifier 1 output | Low-impedance voltage source; requires series isolation resistor (e.g., 27Ω) when driving >100pF capacitive loads |
| 2: –IN1 | Inverting input, Amp 1 | Current-summing node; sensitive to stray capacitance-ground plane must be removed beneath trace |
| 3: +IN1 | Non-inverting input, Amp 1 | High-impedance voltage reference node; must be tied to ground if amplifier unused |
| 4: V– | Negative supply rail | Common return for both amplifiers; decouple with 10µF tantalum + 0.1µF ceramic close to pin |
| 5: V+ | Positive supply rail | Common bias for both amplifiers; identical decoupling required as V– |
| 6: +IN2 | Non-inverting input, Amp 2 | Independent high-Z node; same grounding rule applies as +IN1 |
| 7: –IN2 | Inverting input, Amp 2 | Second current-summing node; layout rules identical to –IN1 for stability |
| 8: OUT2 | Amplifier 2 output | Independent output; supports simultaneous dual-video-path routing without crosstalk degradation |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables bandwidth tuning via RF selection-no fixed gain-bandwidth trade-off like voltage-feedback op-amps |
| 0.1dB gain flatness to 5MHz | Preserves chroma/luma amplitude relationships across composite video spectrum |
| Low input bias current mismatch | ΔIB ≤ 6µA (25°C) ensures matched DC operating points across dual channels for differential video paths |
| High channel separation | >70dB at 10MHz prevents cross-talk between RGB or Y/C signal paths in multi-channel systems |
| Robust short-circuit protection | Withstands continuous 15mA output current per channel-safe for 75Ω load faults |
Applications
| Video Gain Block | Video Distribution Amplifier |

IC Role / Device Role / Timing Role: Dual-channel DC-coupled gain stage providing precise 1× to 10× amplification with minimal group delay variation. Use Value: Maintains 0.03% differential gain/phase integrity across full NTSC/PAL bandwidth, eliminating hue/saturation shift. |
Use Scenario: Splitting one video source to multiple displays or processing units while preserving signal fidelity. IC Role / Device Role / Timing Role: Dual-output buffer driving two independent 75Ω back-terminated coaxial lines simultaneously. Use Value: Delivers matched output drive strength and phase response-critical for synchronized multi-display installations. |
| Flash A/D Driver | Radar Imaging Front-End |
Use Scenario: Driving the input of high-speed flash ADCs (e.g., 50–100MSPS) in medical ultrasound or test equipment. IC Role / Device Role / Timing Role: Low-noise, fast-settling buffer isolating ADC input from source impedance variations. Use Value: 75ns settling to 0.1% ensures accurate sampling of transient pulses without aperture error. |
Use Scenario: Conditioning pulsed RF envelope signals in L-band radar receivers before digitization. IC Role / Device Role / Timing Role: High-slew-rate amplifier shaping IF video pulses with sub-10ns rise/fall times. Use Value: 475V/µs slew rate preserves pulse fidelity for accurate time-of-flight measurement. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| EL8172IWZ | Higher 200MHz bandwidth but higher 1.2mV VOS; SOIC-8, ±5V–±15V supply compatible | Preferred for >100MHz wideband imaging where gain flatness <0.05dB to 10MHz is required | Select EL8172IWZ when bandwidth headroom >75MHz is needed and offset drift tolerance allows >1mV |
| THS3202D | Lower 0.01% differential gain but only single-channel; SOIC-8, requires dual placement for same function | Better for space-constrained PCBs where layout symmetry permits discrete channel duplication | Choose THS3202D only when dual-amplifier integration is not mandatory and board area allows two placements |
Compared with HA5023IBZ, EL8172IWZ offers greater bandwidth at the cost of higher offset and reduced video-specific optimization, while THS3202D trades integration for superior differential gain-but doubles component count and layout complexity.

FAQ
What is the recommended feedback resistor for HA5023IBZ at AV = +2?
The datasheet specifies RF = 681Ω for AV = +2 configuration. This value balances bandwidth (95MHz) and stability-reducing RF further increases peaking risk. Use metal-film chip resistors with tight tolerance (±1%) and low parasitic inductance to preserve pulse fidelity in HA5023IBZ designs.
Can HA5023IBZ drive 75Ω coaxial cables directly?
Yes-HA5023IBZ is characterized to drive two back-terminated 75Ω cables simultaneously. For optimal performance, place a 27Ω isolation resistor in series with each output (per Figure 6) to suppress capacitive-load-induced peaking, especially with long cable runs or unterminated stubs in HA5023IBZ video routing.
Does HA5023IBZ support single-supply operation?
No-HA5023IBZ requires dual ±4.5V to ±15V supplies. Its input common-mode range is specified as ±2.5V with ±5V supplies, and output swing is symmetrical about ground. Single-supply use violates absolute maximum ratings and causes clipping; for single-rail video buffering, consider dedicated rail-to-rail alternatives instead of HA5023IBZ.
How does HA5023IBZ compare to the HA-5020?
The HA5023IBZ delivers identical video performance to the HA-5020 (0.03% DG/DP, 125MHz BW, 475V/µs SR) but in a modern Pb-free SOIC-8 package. It replaces HA-5020 in new designs with no circuit changes-same pinout, same electrical behavior, and guaranteed operation over –40°C to +85°C, making HA5023IBZ the direct drop-in successor to HA-5020.
What thermal derating applies to HA5023IBZ in SOIC package?
SOIC-packaged HA5023IBZ has θJA = 160°C/W. At ±5V supply and full output load, junction temperature must stay below 150°C. With 15mA per channel (150mW dissipation), ambient must remain ≤65°C-use thermal vias under exposed pad (if present) and minimize copper pour near V+/V– pins to sustain HA5023IBZ reliability in enclosed enclosures.
