Product details
Overview
THS4223PWP from Texas Instruments is a triple-channel, rail-to-rail output, high-speed voltage-feedback operational amplifier optimized for low-distortion signal conditioning in data converter interfaces and video systems. It delivers 230 MHz small-signal bandwidth (G = 1), 975 V/µs slew rate, –90 dBc HD2 and –100 dBc HD3 at 5 MHz (RL = 499 Ω), and ±4.8 V output swing into 2 kΩ - enabling high-fidelity analog front-end design for ADC drivers and composite video amplification.
For engineers reviewing the THS4223PWP datasheet, THS4223PWP pinout, THS4223PWP application, or THS4223PWP equivalent, this page provides verified electrical specifications, TSSOP-14 package terminal mapping, real-world use cases in precision signal chains, and two validated alternative parts with documented functional trade-offs for supply-voltage scalability and power-down capability.
Technical Context
The THS4223PWP implements a voltage-feedback architecture with fully differential input stage and rail-to-rail complementary bipolar output stage, supporting stable unity-gain operation. Its 230 MHz bandwidth and 975 V/µs slew rate are achieved under ±5 V supply with 14 mA per channel quiescent current, while maintaining <0.007% differential gain and <0.007° differential phase error in NTSC/PAL video applications.
It operates across single-supply (3–15 V) and dual-supply (±1.35–±7.5 V) configurations, with common-mode input range extending to within 1.1 V of rails. The device includes no internal power-down circuitry - unlike THS4227PWP - and uses fixed reference biasing rather than programmable REF pin control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 230 MHz at G = 1 (±5 V): enables wideband baseband signal amplification without phase degradation up to UHF frequencies. |
| Slew rate | 975 V/µs (min, G = 1, ±5 V): supports full-scale transient response for 10-bit+ ADC sampling at >50 MSPS without slewing-induced distortion. |
| Harmonic distortion | HD2 = –90 dBc, HD3 = –100 dBc @ 5 MHz (RL = 499 Ω): ensures minimal spectral contamination in IF/RF sampling and video reconstruction paths. |
| Rail-to-rail output swing | ±4.8 V into 2 kΩ (±5 V supply): maximizes dynamic range utilization when driving 12-bit+ SAR or pipeline ADCs with 4.096 V reference. |
| Quiescent current | 14 mA per channel (typ, ±5 V): balances speed and power for multi-channel instrumentation where thermal density matters. |
| Differential gain/phase | 0.007% / 0.007° (NTSC/PAL, G = 2): meets broadcast-grade video fidelity requirements without external calibration. |
| Input voltage noise | 13 nV/√Hz @ 1 MHz: contributes <1 LSB noise floor in 16-bit system designs with proper gain staging. |
Pinout & Package
TSSOP-14 (PWP) thermally enhanced surface-mount package with exposed PowerPAD for junction-to-board thermal conduction; 5.0 mm × 6.4 mm footprint, 0.65 mm pitch, 1.2 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Channel 1 terminals: 1IN–, 1IN+, 1OUT | Inverting/non-inverting inputs and output for first op-amp; requires matched trace lengths for high-frequency stability. |
| 4 | VS– | Negative supply rail connection; must be decoupled with 0.1 µF ceramic + 10 µF tantalum near pin. |
| 5, 6, 7 | Channel 2 terminals: 2IN–, 2IN+, 2OUT | Independent second amplifier channel; crosstalk < –90 dB @ 5 MHz enables simultaneous analog channel processing. |
| 8, 9, 10 | Channel 3 terminals: 3IN–, 3IN+, 3OUT | Third independent channel; identical AC/DC specs to Ch1/Ch2 - suitable for RGB video or 3-phase sensor conditioning. |
| 11 | VS+ | Positive supply rail; shared across all three channels; PowerPAD must be soldered to thermal plane for 3.3 W dissipation rating. |
| 12–14 | NC | No internal connection; left floating or grounded per layout best practices to reduce parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers >96% of full supply voltage swing into 2 kΩ loads, preserving SNR headroom in low-voltage ADC driver stages. |
| Triple-channel integration | Reduces board area by 60% vs discrete solutions and eliminates inter-channel gain/phase mismatch in multi-path signal chains. |
| Low harmonic distortion | –100 dBc third-harmonic at 5 MHz enables clean undersampling of IF signals up to 200 MHz without image rejection filters. |
| Video-optimized performance | 0.007° differential phase error meets SMPTE RP-168 spec for professional SD/HD video routing and distribution amplifiers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4227PWP | Includes power-down mode (PD pins 1/2/3), REF pin for threshold adjustment, and higher quiescent current (17 mA/ch at ±5 V). | Required where dynamic power gating is needed in battery-powered portable test equipment or intermittent-scan imaging systems. | Select THS4227PWP only if power-down functionality is mandatory; otherwise THS4223PWP offers lower static power and identical AC performance. |
| OPA2691DGQ | Dual-channel (not triple), 300 MHz bandwidth, 1800 V/µs slew rate, higher input voltage noise (5.5 nV/√Hz), no rail-to-rail output. | Suitable for high-bandwidth, low-noise applications where channel count is secondary and output swing > ±3.5 V is acceptable. | Choose OPA2691DGQ when bandwidth >230 MHz is critical and triple-channel integration is unnecessary; avoid if rail-to-rail output or video fidelity is required. |
Compared with THS4227PWP, THS4223PWP eliminates power-down overhead for always-on systems, reducing complexity and PCB space; versus OPA2691DGQ, it trades 70 MHz bandwidth for triple-channel density, rail-to-rail swing, and superior video linearity - making it optimal for compact multi-channel analog front-ends.

FAQ
What is the maximum supply voltage for THS4223PWP?
The absolute maximum supply voltage for THS4223PWP is ±8.25 V (16.5 V total) or 15 V single-supply, as specified in the Absolute Maximum Ratings table. Operation beyond these limits risks permanent damage. Recommended operating range is ±1.35 V to ±7.5 V dual or 2.7 V to 15 V single supply, with optimal performance observed at ±5 V or 5 V.
Does THS4223PWP support power-down functionality?
No, THS4223PWP does not include power-down circuitry. It is the non-power-down variant of the THS422x triple-amplifier family. The THS4227PWP is the functionally identical part with integrated power-down pins (1PD, 2PD, 3PD) and REF pin for threshold control. THS4223PWP draws 14 mA per channel continuously under ±5 V conditions.
What is the output voltage swing of THS4223PWP into 499 Ω load?
At ±5 V supply, THS4223PWP delivers a minimum output voltage swing of ±4.4 V into 499 Ω (–40°C to +85°C), and ±4.7 V at 25°C. With 2 kΩ load, it achieves ±4.8 V minimum swing - confirming true rail-to-rail capability essential for maximizing ADC dynamic range in precision measurement systems.
Can THS4223PWP drive 75 Ω video loads directly?
THS4223PWP is not rated for continuous 75 Ω driving; its specified output current is ±100 mA (min) into 10 Ω, but sustained 75 Ω loading exceeds safe thermal limits in TSSOP-14 without heatsinking. For 75 Ω video, use 499 Ω series termination with 75 Ω cable and load - a standard practice that maintains signal integrity while keeping junction temperature within 150°C limit.
What is the typical input offset voltage of THS4223PWP?
The typical input offset voltage of THS4223PWP is 3 mV at 25°C, with a maximum of 16 mV over the full –40°C to +85°C temperature range. This specification applies under both dual-supply (±5 V) and single-supply (5 V) conditions, with input common-mode voltage centered at mid-supply (0 V or 2.5 V respectively).
