Product details
Overview
THS4215DRB from Texas Instruments is a unity-gain stable, high-speed voltage feedback operational amplifier with 1 GHz small-signal bandwidth (±5 V), 970 V/µs slew rate, −90 dBc THD at 30 MHz (RL = 499 Ω), and integrated power-down functionality. It operates from ±2.5 V to ±7.5 V dual supplies or 5 V to 15 V single supply, delivering 200 mA output drive and optimized video performance including 0.007% differential gain and 0.003° differential phase - ideal for high-fidelity ADC preamplification and DAC output buffering in test equipment and broadcast video systems.
For engineers reviewing the THS4215DRB datasheet, THS4215DRB pinout, THS4215DRB application, or THS4215DRB equivalent, this page delivers verified electrical specifications, thermal package data (DRB: 8-pin leadless MSOP with PowerPAD™), power-down timing (tON = 4 µs, tOFF = 3 µs), and real-world distortion vs. frequency behavior - all critical for wideband signal chain design requiring low harmonic distortion and fast settling.
Technical Context
The THS4215DRB employs a voltage-feedback architecture with internal compensation enabling stable unity-gain operation without external components. Its high slew rate and wide bandwidth stem from optimized transconductance and low-output-impedance stages, supporting full-power bandwidth up to 77 MHz (G = −1, VO = 2 Vp) under ±5 V supply.
Power-down control is implemented via a dedicated PD pin referenced to either VS− or REF (0 V or VS+), enabling quiescent current reduction from 24 mA to ≤900 µA. The DRB package integrates a thermally enhanced PowerPAD™ on the underside, requiring PCB thermal plane connection to maintain junction temperature ≤125°C during continuous 2.18 W power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 1 GHz at G = 1, ±5 V - enables baseband-to-UHF signal amplification without peaking or instability. |
| Slew rate | 970 V/µs (G = 1, VO = 2 V step) - supports clean 100+ MHz large-signal transient response with minimal slewing distortion. |
| THD @ 30 MHz | −90 dBc (RL = 499 Ω) - ensures <0.003% harmonic contamination in high-linearity ADC driver applications. |
| Differential gain/phase | 0.007% / 0.003° (G = 2, NTSC/PAL) - meets broadcast-grade video fidelity requirements for composite/S-video routing. |
| Power-down current | ≤900 µA (PD = REF−1.5 V, Ref = 5 V) - reduces system standby power while preserving fast 4 µs wake-up for burst-mode operation. |
| Supply range | ±2.5 V to ±7.5 V dual or 5 V to 15 V single - supports legacy ±5 V and modern low-voltage/high-voltage industrial rails. |
| Output drive | 200 mA sourcing (RL = 10 Ω) - drives heavy capacitive loads (e.g., 75 Ω coax + ADC input capacitance) without gain roll-off. |
Pinout & Package
THS4215DRB uses an 8-pin leadless MSOP package with exposed thermal pad (PowerPAD™), requiring solder connection to a PCB copper plane for thermal management. Package dimensions: 3.0 mm × 3.0 mm × 0.8 mm (JEDEC MO-229, variant WD). Pin 1 is marked by a dot; top-side marking is "BEU".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - REF | Reference voltage input | Provides bias reference for power-down threshold; tied to 0 V, VS+, or floating per enable logic. |
| 2 - IN− | Inverting input | Differential input node; high-impedance (4 MΩ common-mode) with 0.3 pF capacitance. |
| 3 - IN+ | Non-inverting input | High-impedance input node; matched to IN− for optimal CMRR (56 dB min at 25°C). |
| 4 - VS− | Negative supply rail | Connects to ground (single-supply) or negative rail; must be decoupled with 0.1 µF ceramic capacitor. |
| 5 - NC | No connect | Internally unused; leave unconnected and unpopulated on PCB. |
| 6 - VS+ | Positive supply rail | Accepts 5–15 V (single) or ±2.5–±7.5 V (dual); requires local 0.1 µF + 4.7 µF decoupling. |
| 7 - VOUT | Amplifier output | Low-impedance (0.3 Ω typical) output capable of ±3.6 V swing into 150 Ω load at 85°C. |
| 8 - PD | Power-down control | Active-high enable: >REF+1.8 V enables; |
Key Features

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 |
|---|---|---|---|
| THS4211DRB | No power-down pin; identical AC/DC specs and pinout except PD/REF pins repurposed as NC. | Lacks standby power control; suitable only for always-on signal paths with no burst-mode requirement. | Select THS4211DRB when system-level power sequencing eliminates need for per-amplifier shutdown. |
| THS4503IDGNR | Fully differential architecture; 1.6 GHz BW, 2.2 V/µs slew, but requires differential input source and matched layout. | Optimized for ADC driver applications with differential inputs (e.g., ADS4149); not pin-compatible. | Choose THS4503IDGNR when driving differential-input ADCs and board space permits differential routing. |
Compared with THS4215DRB, THS4211DRB removes power management at zero AC performance cost, while THS4503IDGNR trades single-ended simplicity for superior CMRR and PSRR in noise-sensitive mixed-signal environments - neither is drop-in replaceable due to pinout and topology differences.

FAQ
What supply voltages does the THS4215DRB support?
The THS4215DRB supports dual supplies from ±2.5 V to ±7.5 V and single supplies from 5 V to 15 V. At ±5 V, it delivers full 1 GHz bandwidth and 970 V/µs slew rate; at 5 V single supply, bandwidth remains 980 MHz with 800 V/µs slew rate. Operation outside these ranges risks parametric degradation or damage.
How does the power-down function work on the THS4215DRB?
The THS4215DRB uses dedicated REF and PD pins: when PD is driven >REF+1.8 V (REF = 0 V or VS−), the amplifier enables; when PD is The THS4215DRB in DRB package features an exposed PowerPAD™ thermal pad requiring solder connection to a minimum 100 mm² internal or external copper plane. With JEDEC High-K board, θJA = 45.8°C/W enables 873 mW continuous power at 85°C ambient. Failure to thermally connect the pad risks junction temperatures exceeding 125°C, causing permanent performance loss. Yes - the THS4215DRB delivers 200 mA output current and maintains 0.007% differential gain / 0.003° differential phase into 150 Ω loads (standard for dual-terminated video), making it suitable for direct 75 Ω driving with appropriate series termination. Output voltage swing remains ±3.6 V min at 85°C into 150 Ω, sufficient for 1 VPP video levels. At G = 2, the THS4215DRB achieves 325 MHz small-signal bandwidth (±5 V, RL = 499 Ω) and 130 MHz 0.1 dB flat bandwidth - confirmed in both datasheet Figure 2 and Table 1. This supports high-fidelity amplification of IF signals up to 100 MHz with minimal gain variation and phase distortion.What is the thermal requirement for the THS4215DRB DRB package?
