Product details
Overview
THS4215DGN from Texas Instruments is a low-distortion, high-speed voltage-feedback amplifier with power-down functionality, designed for precision analog signal conditioning in wideband applications. It delivers 970 V/µs slew rate, 1 GHz small-signal bandwidth (±5 V), –90 dBc THD at 30 MHz (G = 1), 0.007% differential gain, and ±5 V or single 5–15 V operation - enabling high-fidelity ADC preamplification and video signal buffering.
For engineers reviewing the THS4215DGN datasheet, THS4215DGN pinout, THS4215DGN application, or THS4215DGN equivalent, key selection criteria include power-down quiescent current (≤1 mA), 8-pin MSOP-PowerPAD™ package thermal performance, harmonic distortion vs. frequency behavior, and compatibility with ±5 V or 5 V single-supply video/communications signal chains.
Technical Context
The THS4215DGN employs a unity-gain-stable voltage-feedback architecture optimized for wideband linearity and fast settling (22 ns to 0.1%). Its internal compensation enables stable operation at G ≥ 1 without external feedback tuning, while the dedicated PD pin provides TTL/CMOS-compatible power-down control with 4 µs turn-on and 3 µs turn-off delays.
It features matched input impedance (4 MΩ common-mode), low input capacitance (0.3 pF common-mode), and output drive capability up to 220 mA sourcing (±5 V, RL = 10 Ω). The PowerPAD™ thermal pad requires PCB copper connection to maintain junction temperature ≤125°C under full load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 1 GHz at ±5 V supply - supports RF/IF signal amplification up to L-band without gain peaking. |
| Slew rate | 970 V/µs - preserves fidelity of fast transient signals like radar pulses or high-speed DAC outputs. |
| THD @ 30 MHz | –90 dBc (G = 1, VO = 1 VPP, RL = 499 Ω) - meets broadcast video and medical imaging linearity requirements. |
| Differential gain/phase | 0.007% / 0.003° - ensures minimal color error in NTSC/PAL composite video distribution. |
| Power-down current | ≤900 µA (±5 V) - enables dynamic power gating in battery-sensitive or multi-channel systems. |
| Supply range | ±2.5 V to ±7.5 V dual or 5 V to 15 V single - interoperable with legacy ±5 V and modern 5 V/12 V industrial rails. |
| Input voltage noise | 7 nV/√Hz at 1 MHz - critical for low-noise preamplifier stages preceding high-resolution ADCs. |
Pinout & Package
The THS4215DGN is housed in an 8-pin MSOP package with exposed PowerPAD™ thermal pad on the underside, requiring soldered thermal connection to PCB ground plane for rated power dissipation (1.71 W at TA ≤ +25°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connection | Internally unconnected; must remain floating or grounded per layout guidelines. |
| 2 (IN–) | Inverting input | Differential input node; high-impedance (4 MΩ), low-capacitance (0.3 pF) interface to feedback network. |
| 3 (IN+) | Non-inverting input | High-impedance input node; matched to IN– for optimal CMRR (56 dB min at ±1 V). |
| 4 (VS–) | Negative supply rail | Connects to negative supply (e.g., –5 V); decoupling capacitor required within 1 cm. |
| 5 (NC) | No Connection | Internally unconnected; no routing or termination needed. |
| 6 (VS+) | Positive supply rail | Connects to positive supply (e.g., +5 V); decoupling capacitor required within 1 cm. |
| 7 (VOUT) | Amplifier output | Capable of ±4.0 V swing into 499 Ω; drives 150 Ω video loads with <0.01° phase error. |
| 8 (PD) | Power-down control | Active-high logic input; >REF+1.0 V enables, |
Key Features
| Feature | Design Value |
|---|---|

| Video-optimized linearity | 0.007% differential gain and 0.003° differential phase meet SMPTE 253M broadcast standards for SD/HD video. |
| Thermally enhanced package | MSOP-8 with PowerPAD™ achieves θJA = 58.4°C/W - enables 685 mW continuous power at +85°C ambient. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed voltage-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4211DGN | No power-down pin; identical AC/DC specs and pinout except PD pin repurposed as NC. | Lacks dynamic power gating - unsuitable for duty-cycled or portable systems requiring standby current <1 mA. | Select THS4211DGN only when power-down functionality is unnecessary and BOM consolidation is prioritized. |
| LMH6702MF/NOPB | Higher 1.7 GHz bandwidth but higher 12.5 mA quiescent current; no integrated power-down. | Better small-signal speed but inferior power efficiency and video linearity (0.02% DG vs. 0.007%). | Choose LMH6702MF/NOPB only for >1 GHz small-signal gain-flatness-critical applications where power budget allows. |
Compared with THS4211DGN and LMH6702MF/NOPB, THS4215DGN uniquely balances 1 GHz bandwidth, –90 dBc THD, and sub-mA power-down current in an MSOP-PowerPAD™ package - making it optimal for space-constrained, multi-channel video and instrumentation systems requiring dynamic power control.

FAQ
What is the maximum recommended supply voltage for THS4215DGN?
The absolute maximum supply voltage for THS4215DGN is ±8.25 V (16.5 V total), but the recommended operating range is ±2.5 V to ±7.5 V for dual supply or 5 V to 15 V for single supply. Operating beyond ±7.5 V risks exceeding safe junction temperature and degrading distortion performance, especially above 125°C.
How does the power-down function behave on THS4215DGN?
The THS4215DGN enters low-power mode when the PD pin voltage falls below REF–1.5 V (REF = VS+ or floating) or rises above REF+1.0 V (REF = VS– or 0 V), reducing quiescent current to ≤900 µA. Output goes high-impedance, and turn-off delay is 3 µs; turn-on delay is 4 µs to 50% of final supply current.
Can THS4215DGN operate from a single 5-V supply?
Yes, THS4215DGN supports single 5-V operation with input common-mode range of 1.2 V to 3.8 V and output swing of 1.2 V to 3.8 V (RL = 499 Ω). Performance metrics such as 300 MHz small-signal bandwidth and –60 dBc THD at 30 MHz are specified under 5-V conditions, confirming full functionality.
What thermal design considerations apply to THS4215DGN's MSOP-PowerPAD™ package?
The THS4215DGN's MSOP-PowerPAD™ requires the exposed thermal pad to be soldered to a minimum 100 mm² PCB copper area connected to ground. Without this, θJA rises from 58.4°C/W to >100°C/W, risking junction temperatures >125°C at >400 mW dissipation - which triggers distortion increase and reliability degradation.
Is THS4215DGN pin-compatible with THS4211DGN?
Yes, THS4215DGN and THS4211DGN share identical 8-pin MSOP-PowerPAD™ footprints and pin assignments except Pin 8: THS4215DGN uses it as PD (power-down control), while THS4211DGN designates it as NC. A direct PCB replacement is possible only if the PD net is left unconnected or pulled to valid enable/disable voltage.
