Product details
Overview
THS4501CDGN from Texas Instruments is a high-performance fully differential amplifier optimized for ADC driving, single-ended-to-differential conversion, and active filtering in RF and communications systems. It delivers 370 MHz small-signal bandwidth, –90 dBc third-order intermodulation distortion at 30 MHz, 2800 V/μs slew rate, and output common-mode voltage control (VOCM) with ±5 V or single 5 V supply operation - enabling high-fidelity signal conditioning in 12-bit/80 MSps data acquisition chains.
For engineers reviewing the THS4501CDGN datasheet, THS4501CDGN pinout, THS4501CDGN application, or THS4501CDGN equivalent, this device is selected for demanding analog front-end designs requiring ultra-low distortion, wide bandwidth, rail-included input common-mode range, and precise differential output balance - especially where ESD-robust, thermally enhanced MSOP-8 packaging is critical.
Technical Context
The THS4501CDGN implements a fully differential architecture with independent VOCM input for precise output common-mode setting, supporting both single-ended and differential inputs. Its input stage shifts the common-mode range to include the negative supply rail (–5.7 V at ±5 V), enabling direct interfacing with ground-referenced sources without level-shifting circuitry.
Internally, it features a high-slew-rate transconductance stage followed by a low-impedance differential output buffer. The device lacks power-down functionality (distinguishing it from THS4500), operates over –40°C to +85°C (I-suffix), and uses TI's PowerPAD-enhanced MSOP-8 package for superior thermal dissipation and ac performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 370 MHz at ±5 V supply - supports wideband IF sampling up to 40 MHz while maintaining 14-bit linearity. |
| Third-order IMD | –90 dBc at 30 MHz (200 kHz tone spacing) - ensures clean spectral purity in wireless receiver chains. |
| Slew rate | 2800 V/μs - enables faithful reproduction of fast transient signals without slewing-induced distortion. |
| OIP3 | 49 dBm at 30 MHz - provides high dynamic range for handling large interferers in crowded RF environments. |
| Input voltage noise | 7 nV/√Hz above 1 MHz - minimizes added noise in precision gain stages preceding high-resolution ADCs. |
| Common-mode input range | –5.7 V to +2.6 V at ±5 V - accepts ground-referenced inputs without external biasing or level shifters. |
| Differential output swing | ±7.4 V into 1 kΩ load at ±5 V - drives ADC inputs with full-scale headroom and low THD. |
Pinout & Package
The THS4501CDGN is housed in an 8-pin MSOP package with PowerPAD™ thermal pad on the underside, requiring connection to a PCB thermal plane for optimal junction temperature control and long-term reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN− | Inverting input | Accepts differential or single-ended input; common-mode range extends to VS− rail. |
| VIN+ | Non-inverting input | Paired with VIN− for fully differential operation; supports DC-coupled signal paths. |
| VOCM | Output common-mode control | Programs output common-mode voltage (e.g., 2.5 V for 5 V ADC reference); input impedance 25 kΩ||1 pF. |
| VS+ | Positive supply | Accepts +5 V (single) or +5 V (dual); max rating 7.5 V; PSRR+ = 75 dB min at 5 V. |
| VOUT+ | Positive differential output | Delivers amplified, balanced output; output balance error ≤ –58 dB at 100 kHz. |
| VS− | Negative supply | Required for dual-supply operation (–5 V); also serves as reference for input common-mode range. |
| VOUT− | Negative differential output | Complementary to VOUT+; maintains tight amplitude/phase matching for low even-order distortion. |
| NC | No connect | Pin 5 is unconnected (not PD like THS4500); confirms absence of power-down function in THS4501 variant. |
Key Features
| Feature | Design Value |
|---|---|
| Fully differential architecture | Eliminates even-order harmonics and common-mode noise, improving SNR in ADC interfaces. |
| Output common-mode voltage control (VOCM) | Allows precise alignment of differential output to ADC reference (e.g., 2.5 V), reducing offset errors. |
| Rail-inclusive input common-mode range | Accepts inputs down to VS−, enabling direct connection to ground-referenced sensors or DACs. |
| PowerPAD-enhanced MSOP-8 package | Reduces θJA to 58.4°C/W and increases power dissipation to 1.71 W at TA ≤ 25°C for stable high-speed operation. |
| Wide supply range support | Operates from ±5 V, ±7.5 V, or single 4.5–15 V - simplifies system-level power architecture across platforms. |
Applications
| Wireless Communication Receiver Chains | Analog-to-Digital Converter Preamplifier |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fully differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4500CDGN | Includes power-down pin (PD); otherwise identical bandwidth, distortion, and pinout. | Required where system-level power gating or standby mode is needed. | Select THS4500CDGN only if explicit power-down control is required; THS4501CDGN offers lower quiescent current in active mode (20 mA vs 23 mA at 5 V). |
| THS4130IDGK | Lower bandwidth (150 MHz), higher supply voltage (±15 V), lower noise (1.3 nV/√Hz), no VOCM input. | Suited for high-voltage, low-noise precision instrumentation, not RF/ADC driving. | Choose THS4130IDGK for ±15 V systems needing ultra-low noise; avoid for VOCM-dependent ADC interfaces or >200 MHz signal paths. |
Compared with THS4500CDGN, THS4501CDGN eliminates power-down complexity and reduces active quiescent current; compared with THS4130IDGK, it trades voltage headroom and noise for RF-grade bandwidth, VOCM control, and 5 V compatibility - making it uniquely suited for modern high-speed data converter interfaces.

FAQ
What is the maximum supply voltage for THS4501CDGN?
The THS4501CDGN supports a maximum supply voltage of ±7.5 V in dual-supply mode or 15 V in single-supply mode, per its Absolute Maximum Ratings table. Operation beyond these limits risks permanent damage. For reliable 14-bit performance, TI specifies nominal operation at ±5 V or 5 V, where key parameters like bandwidth and IMD3 are characterized.
Does THS4501CDGN support single-ended input configurations?
Yes, THS4501CDGN supports single-ended input operation - its fully differential architecture accepts single-ended signals applied to either VIN+ or VIN− while grounding the other, with the input common-mode range extending to the negative supply rail. This enables direct interface with single-ended DACs or sensors without external level-shifting components.
How does the VOCM pin function in THS4501CDGN?
The VOCM pin on THS4501CDGN sets the output common-mode voltage - for example, applying 2.5 V to VOCM forces VOUT+ and VOUT− to swing symmetrically around 2.5 V. This feature is essential for matching ADC reference voltages and minimizing offset errors. VOCM has 25 kΩ input impedance and operates linearly across 1.3 V to 3.7 V at 5 V supply.
Is THS4501CDGN pin-compatible with THS4500CDGN?
Yes, THS4501CDGN is pin-compatible with THS4500CDGN in the same DGN (MSOP-8 PowerPAD) package: both share identical pin assignments except Pin 5, which is NC on THS4501CDGN and PD (power-down) on THS4500CDGN. No PCB layout change is required when substituting THS4501CDGN for THS4500CDGN in non-power-down applications.
What thermal considerations apply to THS4501CDGN's PowerPAD package?
The THS4501CDGN's MSOP-8 PowerPAD requires soldering the exposed thermal pad to a dedicated PCB copper pour connected to ground or a thermal plane. Without this, θJA rises to 260°C/W (vs. 58.4°C/W with proper thermal design), risking junction temperatures exceeding +125°C - where distortion increases and long-term reliability degrades. TI recommends minimum 4×4 mm² thermal pad area with ≥4 thermal vias.
