Product details
Overview
THS4504DR from Texas Instruments is a wideband, low-distortion fully differential amplifier with power-down capability, designed as a high-linearity ADC driver for 12-bit/80-MSps data acquisition systems. It delivers 260 MHz small-signal bandwidth, –73 dBc IMD3 at 30 MHz, and 29 dBm OIP3 under ±5-V supply, enabling precision signal conditioning in wireless receiver chains and active differential filtering.
For engineers reviewing the THS4504DR datasheet, THS4504DR pinout, THS4504DR application, or THS4504DR equivalent, this page provides verified specifications, SOIC-8 package details, power-down timing behavior, VOCM-controlled common-mode output, and validated alternatives for high-speed analog front-end design.
Technical Context
The THS4504DR implements a fully differential architecture with independent input common-mode range extending to the negative rail (–5.7 V at ±5 V supply) and precise output common-mode voltage control via the VOCM pin. Its high slew rate (1800 V/µs) and low distortion support fast settling of large differential transients into high-resolution ADCs.
Power-down functionality is implemented via a dedicated PD pin with defined enable/disable thresholds (≥ –2.9 V ON, ≤ –4.3 V OFF), delivering <1.2 mA quiescent current in shutdown while maintaining high input impedance (50 kΩ || 1 pF) and sub-µs turn-on/turn-off delays (1000 ns / 800 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 260 MHz at G = 1 (±5 V), enabling baseband-to-IF signal amplification up to UHF without gain peaking. |
| Slew rate | 1800 V/µs (±5 V), supporting full-scale 4-VPP differential steps with <1 ns rise/fall time for clean transient response. |
| IMD3 distortion | –73 dBc at 30 MHz (200 kHz tone spacing), ensuring minimal intermodulation in multi-carrier wireless receivers. |
| OIP3 | 29 dBm at 30 MHz (referred to 50 Ω), confirming robust linearity for high-dynamic-range RF sampling applications. |
| Power-down current | ≤1200 µA max (±5 V), reducing system standby power without compromising wake-up latency or input protection. |
| Input CM range | –5.7 V to +2.6 V (±5 V), allowing direct interfacing with single-ended sources referenced to negative rails or ground. |
| VOCM control bandwidth | 200 MHz small-signal BW (RL = 400 Ω), permitting fast common-mode adjustment during dynamic gain or level-shifting sequences. |
Pinout & Package
THS4504DR is supplied in an 8-pin SOIC package (D package), with exposed pad thermally isolated per TI PowerPAD™ specification. Pin 1 is VIN−; pin 2 is VIN+; pin 3 is VOCM; pin 4 is VS+; pin 5 is VOUT+; pin 6 is PD; pin 7 is VS−; pin 8 is VOUT−. Pin 6 (PD) enables hardware-controlled power-down; pins 1–8 are electrically defined per TI SLOS363D revision May 2008.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN− | Inverting input | Differential input node; accepts signals down to –5.7 V (±5 V supply), enabling rail-to-rail input common-mode operation. |
| VIN+ | Non-inverting input | Differential input node; complements VIN− for true differential signaling and common-mode rejection >70 dB. |
| VOCM | Output common-mode control | Directly sets DC offset of differential outputs; supports 0–5 V range and defaults to ~0 V when floating (±5 V supply). |
| VS+ | Positive supply | Accepts +5 V, +12 V, or +15 V (single-supply) or ±5 V, ±7.5 V (dual-supply); max rating 16.5 V absolute. |
| VOUT+ | Positive differential output | Delivers amplified, phase-aligned output; swing ±7.4 V into 1-kΩ load (±5 V), balanced within –65 dB at 100 kHz. |
| PD | Power-down enable | Active-low logic input; pulls device into low-current state (<1.2 mA) with 800 ns turn-off delay and 1000 ns turn-on delay. |
| VS− | Negative supply | Required for dual-supply operation; supports –5 V to –7.5 V; must be connected even in single-supply mode (tied to GND). |
| VOUT− | Negative differential output | Complementary output to VOUT+; maintains amplitude/phase symmetry critical for ADC sampling integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Fully differential architecture | Eliminates even-order harmonics and improves PSRR/CMMR over single-ended amps, directly enhancing ADC SNR. |
| Power-down capability | Reduces quiescent current from 25 mA to ≤1.2 mA with sub-microsecond switching, ideal for burst-mode or battery-powered systems. |
| Output common-mode control (VOCM) | Enables precise DC-level alignment of differential outputs to match ADC input requirements without external resistive dividers. |
| Rail-to-rail input common-mode range | Supports inputs down to VS− (–5.7 V at ±5 V), simplifying interface with sensors, DACs, or legacy op-amp stages. |
| High OIP3 and low IMD3 | Ensures minimal spectral regrowth in wideband receivers-critical for LTE/WiMAX/5G NR front-end linearity compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fully differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4505DR | No power-down pin; otherwise identical AC/DC specs, pinout, and SOIC-8 packaging. | Preferred where continuous operation is required and power gating adds complexity or risk. | Select THS4505DR only if power-down functionality is unnecessary-no layout change needed but no standby current reduction. |
| THS4521DR | Lower bandwidth (1.8 GHz GBW vs 260 MHz), higher supply current (28 mA vs 25 mA), and no VOCM pin-uses fixed internal common-mode reference. | Better suited for DC-coupled, ultra-high-speed applications where VOCM flexibility is not required. | Choose THS4521DR only when >1-GHz small-signal BW is mandatory and VOCM control can be omitted from system architecture. |
Compared with THS4505DR (no power-down) and THS4521DR (no VOCM, higher BW), THS4504DR uniquely combines hardware-controllable shutdown, precise VOCM adjustment, and 260-MHz bandwidth-making it optimal for power-aware, high-linearity ADC driver designs requiring flexible common-mode management.

FAQ
What is the maximum supply voltage rating for THS4504DR?
The THS4504DR has an absolute maximum supply voltage rating of 16.5 V across VS+ and VS− terminals. Operation beyond this limit risks permanent damage. For reliable long-term performance, TI specifies a maximum operating supply of ±7.5 V (dual) or 15 V (single), with thermal derating applied above +85°C ambient.
Does THS4504DR require external compensation components?
No, THS4504DR is internally compensated and stable for gains ≥ +1 with standard feedback networks (e.g., RF = RG = 499 Ω). No external compensation capacitors or resistors are needed for unity-gain stable operation, simplifying PCB layout and reducing bill-of-materials count.
How does the VOCM pin function in THS4504DR?
The VOCM pin on THS4504DR directly sets the DC common-mode voltage of both differential outputs (VOUT+ and VOUT−). When driven with a stable voltage (e.g., 2.5 V), it forces the output midpoint to that value-enabling seamless interfacing with ADCs requiring specific input common-mode levels without external resistor dividers.
What is the typical power-down quiescent current of THS4504DR?
The typical power-down quiescent current of THS4504DR is 800 µA at ±5 V supply, with a maximum of 1200 µA over temperature. This represents >95% reduction from normal-operation current (25 mA max), making it highly effective for duty-cycled or battery-constrained systems.
Can THS4504DR operate from a single 5-V supply?
Yes, THS4504DR supports single-supply operation at 5 V. In this configuration, VS− is connected to ground, VS+ to +5 V, and VOCM is typically biased at 2.5 V. Input common-mode range becomes –0.7 V to +2.6 V, and differential output swing is ±2.8 V into 1-kΩ load-fully compatible with 3.3-V or 5-V ADCs.
