Product details
Overview
THS4552IPWR from Texas Instruments is a dual-channel, fully differential amplifier optimized for precision ADC driving, featuring 150 MHz small-signal bandwidth (G = 1), 220 V/µs differential slew rate, ±175 µV max input offset voltage at 25°C, and rail-to-rail output with negative-rail input capability - enabling direct dc-coupled interfacing to single-supply SAR and delta-sigma ADCs such as the ADS1278 and ADS8694.
For engineers reviewing the THS4552IPWR datasheet, THS4552IPWR pinout, THS4552IPWR application, or THS4552IPWR equivalent, this page delivers verified specifications, TSSOP-16 package terminal mapping, real-world ADC driver use cases, and validated alternative options - all grounded in TI's SBOS831B production data sheet and official device characterization.
Technical Context
The THS4552IPWR implements a high-speed, low-noise, fully differential architecture with independent VOCM control per channel, supporting wide common-mode output range (0.7 V to >3.0 V) to match diverse ADC input requirements across 1.8 V–5 V supplies. Its negative-rail input stage enables ground-centered, dc-coupled source interfacing without level-shifting circuitry.
Each channel integrates power-down logic (PD1/PD2), dual feedback paths (FB1±/FB2±), and robust capacitive load drive capability - characterized over –40°C to +125°C and specified for stable operation with 1 kΩ loads and 50 Ω source matching. The device maintains <50 ns 0.01% settling for 4 V step inputs and achieves –139 dBc HD3 at 100 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal BW (G = 1) | 150 MHz - supports high-fidelity signal conditioning up to Nyquist of 75 MSPS ADCs without gain-dependent bandwidth collapse. |
| Differential slew rate | 220 V/µs - ensures full-scale transient fidelity for fast-settling 18-bit+ SAR ADC drivers (e.g., ADS8694). |
| Input offset voltage | ±175 µV max at 25°C - enables accurate dc-coupled measurement in 20-bit delta-sigma systems (e.g., ADS1278) without trimming. |
| Input voltage noise | 3.3 nV/√Hz - preserves SNR in high-resolution data acquisition chains where amplifier noise dominates total system noise floor. |
| HD3 @ 100 kHz | –139 dBc at 2 VPP - minimizes harmonic contamination in spectral-sensitive applications like vibration monitoring and precision metrology. |
| Supply range | 2.7 V to 5.4 V single supply - simplifies power architecture in portable and industrial DAQ systems using 3.3 V or 5 V rails. |
| Quiescent current | 1.37 mA per channel at 5 V - balances performance and power efficiency for battery-aware or thermally constrained designs. |
Pinout & Package
THS4552IPWR is packaged in a 16-pin TSSOP (PW package), with exposed pad not electrically connected but requiring thermal connection to PCB ground or power plane per TI layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PD1) | Channel 1 power-down control | Logic-high enables normal operation; logic-low reduces quiescent current to ≤5 µA - critical for low-power sleep modes in portable DAQ. |
| 2 (IN1+) | Channel 1 noninverting input | Accepts single-ended or differential input signals; supports negative-rail input down to VS– – 0.1 V for dc-coupled ground-referenced sources. |
| 3,4 (VS1+) | Channel 1 positive supply | Shared positive rail for both channels; must be decoupled locally with ≥0.1 µF ceramic capacitor near pin. |
| 5 (PD2) | Channel 2 power-down control | Independent enable/disable for second channel - enables asymmetric power management in multi-channel sensor interfaces. |
| 6 (IN2+) | Channel 2 noninverting input | Matches IN1+ electrical behavior; allows simultaneous dual-sensor conditioning without cross-talk degradation (–80 dBc typical). |
| 7 (IN2–) | Channel 2 inverting input | Completes differential input pair; common-mode range extends to VS– – 0.1 V, enabling true dc-coupled bipolar signal handling. |
| 8 (VOCM2) | Channel 2 output common-mode control | Analog input setting average DC level of differential outputs; supports programmable biasing for ADCs with varying VCM requirements (0.7–3.0+ V). |
| 9,10 (VS2+) | Channel 2 positive supply | Electrically tied to pins 3/4 in standard configuration; separate routing recommended only for ultra-low-noise isolation. |
| 11 (VOCM1) | Channel 1 output common-mode control | Independent VCM setting per channel - essential when driving two ADCs with different reference voltages or supply domains. |
| 12,13 (OUT2+, OUT1+) | Positive differential outputs | Deliver rail-to-rail swing (VS– + 0.2 V to VS+ – 0.2 V); require matched trace lengths and impedance control for optimal CMRR preservation. |
| 14,15 (OUT1–, OUT2–) | Negative differential outputs | Complement positive outputs; differential pair must be routed as tightly coupled microstrip to minimize skew and EMI susceptibility. |
| 16 (VS1–/VS2–) | Shared negative supply | Single ground or negative rail connection for both amplifiers; requires low-impedance return path to maintain PSRR >93 dB. |
Key Features
| Feature | Design Value |
|---|---|
| Negative-rail input (NRI) | Enables direct dc-coupling of ground-centered sensors (e.g., strain gauges, thermocouples) to single-supply ADCs without external level shifters. |
| Rail-to-rail output (RRO) | Maximizes dynamic range utilization in low-voltage ADC systems (e.g., 1.8 V or 3.3 V supplies), improving effective resolution by up to 1.5 bits. |
| Wide VOCM control range | Supports output common-mode voltages from 0.7 V to >3.0 V - matches ADS127L01, ADS8694, and other modern precision ADCs with flexible VCM inputs. |
| 18-bit settling time | <500 ns for 4 V step - meets timing budgets of high-speed 18-bit SAR converters operating at ≥1 MSPS sampling rates. |
| Low distortion (HD2/HD3) | –128 dBc / –139 dBc at 100 kHz - preserves SFDR in spectral analysis applications such as power quality monitoring and audio test equipment. |
| Power-down mode | Reduces per-channel IQ to ≤5 µA - extends battery life in portable instrumentation and enables channel-gating in multi-sensor arrays. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4522IPWR | 145 MHz BW, 5.6 nV/√Hz input noise, higher THD (–120 dBc HD2), same TSSOP-16 pinout | Lower precision; suitable for 16-bit SAR or cost-sensitive 18-bit systems where SNR margin is relaxed | Select THS4522IPWR when 150 MHz BW and 3.3 nV/√Hz noise are unnecessary and BOM cost reduction is prioritized. |
| THS4551IRGET | Same 150 MHz BW and 3.3 nV/√Hz noise, but single-channel VQFN-16 package; no PD pin | Requires two units for dual-channel needs; lacks independent power-down per channel | Choose THS4551IRGET only for space-constrained single-channel designs where channel independence is not required. |
Compared with THS4552IPWR, THS4522IPWR trades 5 MHz bandwidth and 2.3 nV/√Hz noise for lower cost and proven manufacturability, while THS4551IRGET sacrifices dual-channel integration and power-down flexibility to reduce footprint - making THS4552IPWR the optimal choice for precision dual-channel, low-power, dc-coupled ADC interface applications.

Does the THS4552IPWR support single-supply operation?
Yes, the THS4552IPWR supports true single-supply operation from 2.7 V to 5.4 V. Its negative-rail input (NRI) and rail-to-rail output (RRO) stages allow dc-coupled interfacing to ground-referenced sources and compatibility with 3.3 V or 5 V ADCs - confirmed in Section 6.3 Recommended Operating Conditions of the THS4552IPWR datasheet.
How does the VOCM pin function in the THS4552IPWR?
The VOCM pin on the THS4552IPWR sets the average DC voltage of the differential output pair. When driven with a stable voltage (e.g., 2.5 V), it configures the output common-mode level precisely - enabling seamless interfacing with ADCs requiring specific VCM inputs (0.7 V to >3.0 V). Gain from VOCM to output average is 0.997–1.001 V/V, with 15 nV/√Hz noise contribution.
Is the THS4552IPWR pin-compatible with any legacy devices?
Yes, the THS4552IPWR is explicitly documented as a pin-compatible upgrade to the THS4522 in TSSOP-16 packaging (Section 2 Applications, SBOS831B). Both share identical pin functions and mechanical footprint, allowing drop-in replacement where improved bandwidth (150 → 145 MHz), lower noise (3.3 → 5.6 nV/√Hz), and better distortion (–139 → –120 dBc HD3) are needed.
What is the power-down current consumption of the THS4552IPWR?
In power-down mode (PD pin logic low), the THS4552IPWR draws ≤5 µA per channel, as specified in Section 6.5 Electrical Characteristics. This ultra-low standby current enables energy-efficient operation in battery-powered DAQ systems and allows selective channel shutdown without affecting adjacent circuitry.
