Product details
Overview
THS4552IPWT from Texas Instruments is a dual-channel, low-noise, precision fully differential amplifier (FDA) with 150 MHz small-signal bandwidth, 220 V/µs differential slew rate, and rail-to-rail output. It features negative-rail input (NRI), wide VOCM control range (0.7 V to >3.0 V), and operates from 2.7 V to 5.4 V single supply. It is optimized for driving high-precision delta-sigma and SAR ADCs in data acquisition systems.
For engineers reviewing the THS4552IPWT datasheet, THS4552IPWT pinout, THS4552IPWT application, or THS4552IPWT equivalent, key selection criteria include its 3.3 nV/√Hz input voltage noise, ±175 µV max input offset at 25°C, 18-bit settling time <500 ns, –139 dBc HD3 at 100 kHz, and support for dc-coupled ground-centered source interfacing to single-supply ADCs.
Technical Context
The THS4552IPWT implements a fully differential architecture with independent VOCM inputs per channel, enabling precise common-mode level setting for mismatched ADC input requirements. Its NRI topology allows direct dc coupling of ground-referenced sensors without level-shifting circuitry.
Each channel integrates power-down logic (PD1/PD2), supports capacitive load driving up to 200 pF, and maintains >85 dB differential-mode-to-common-mode output balance across frequency. The device is characterized from –40°C to +125°C and specified for both 3 V and 5 V operation with consistent AC/DC performance scaling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Small-signal bandwidth | 150 MHz at G = 1 - enables accurate amplification of signals up to Nyquist for ≥300 MSPS sampling systems |
| Differential slew rate | 220 V/µs - supports fast transient response for high-fidelity 16–24-bit ADC driver applications |
| Input voltage noise | 3.3 nV/√Hz - preserves SNR when driving high-resolution delta-sigma ADCs like ADS1278 |
| Input offset voltage (max) | ±175 µV at 25°C - ensures minimal dc error contribution in precision measurement front-ends |
| HD3 @ 100 kHz | –139 dBc at 2 VPP - maintains SFDR >110 dB in high-dynamic-range data acquisition paths |
| Supply range | 2.7 V to 5.4 V single supply - simplifies power design in portable and industrial systems with mixed-voltage rails |
| Settling time (18-bit) | <500 ns to 4 V step - meets timing budgets for fast SAR ADCs such as ADS8694 (0.5 MSPS) |
Pinout & Package
THS4552IPWT is packaged in a 16-pin TSSOP (PW package) with exposed thermal pad not electrically connected; soldering the pad to PCB ground improves thermal performance. Pin functions are validated per TI SBOS831B datasheet Figure 5-2 and Table 5-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1+, IN1− | Channel 1 differential input | Accepts single-ended or differential input; NRI capability allows ground-referenced sensor connection |
| OUT1+, OUT1− | Channel 1 differential output | Drives ADC differential inputs with rail-to-rail swing and matched phase/amplitude |
| VOCM1 | Channel 1 common-mode control | Sets output common-mode voltage independently; supports ADCs with 0.7–3.0 V CM requirement |
| PD1 | Channel 1 power-down enable | Logic-high = active; logic-low = 1 µA quiescent current - enables dynamic power gating per channel |
| VS1+, VS1− | Channel 1 supply pins | Separate supply connections allow independent biasing or noise isolation between channels |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar fully differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4522IPW | 145 MHz BW, 5.6 nV/√Hz noise, 1.14 mA/ch IQ, same 16-pin TSSOP footprint | Lower bandwidth and higher noise limit use in ≤16-bit, ≤1 MSPS systems; lacks VOCM bandwidth spec above 8 MHz | Select THS4522IPW only if cost sensitivity outweighs need for 150 MHz BW and 3.3 nV/√Hz noise in 24-bit DAQ |
| THS4551IRGT | Single-channel version in 16-pin QFN; identical AC/DC specs except no PD2/VOCM2 | Requires two devices for dual-channel use; QFN offers better thermal performance but no TSSOP pin compatibility | Choose THS4551IRGT when board space permits separate ICs or when channel independence justifies layout redesign |
Compared with THS4522IPW, THS4552IPWT delivers 5 MHz higher bandwidth and 2.3 nV/√Hz lower noise-critical for 24-bit delta-sigma systems-while THS4551IRGT trades dual-channel integration for thermal advantage and single-channel optimization.

FAQ
What is the maximum operating temperature range for the THS4552IPWT?
The THS4552IPWT is fully specified from –40°C to +125°C ambient temperature. All electrical characteristics-including input offset voltage drift (±2.0 µV/°C max), bandwidth, and distortion-are guaranteed across this range, making it suitable for under-hood automotive and industrial control applications where thermal stability is critical. THS4552IPWT maintains 150 MHz bandwidth and –139 dBc HD3 even at +125°C.
Does the THS4552IPWT support single-supply operation with ground-referenced inputs?
Yes, the THS4552IPWT features negative-rail input (NRI) architecture, allowing its inputs to operate down to the negative supply rail (VS−). This enables direct dc coupling of ground-referenced sensors-such as bridge-based strain gauges or thermistors-without external level-shifting circuitry. THS4552IPWT achieves this while maintaining >90 dB CMRR and ±175 µV max input offset at 25°C.
How does the VOCM pin function in the THS4552IPWT, and what is its bandwidth?
The VOCM pin in THS4552IPWT sets the average output common-mode voltage for each channel independently. It has a small-signal bandwidth of 40 MHz and large-signal bandwidth of 8 MHz, supporting dynamic common-mode adjustment in real-time systems. THS4552IPWT uses VOCM to match ADC-specific requirements (e.g., 0.7 V for low-voltage ADCs or >3.0 V for 5 V systems), with 0.997–1.001 V/V gain and <15 mV default offset when left open.
Can the THS4552IPWT drive heavy capacitive loads typical of ADC input networks?
Yes, the THS4552IPWT is explicitly characterized for robust capacitive load driving, supporting up to 200 pF directly at its outputs without stability degradation. Its internal compensation and rail-to-rail output stage ensure monotonic settling and minimal overshoot-even into 22 nF filter networks used with ADS127L01-making THS4552IPWT ideal for anti-aliasing filter interfaces in high-precision DAQ designs.
Is the THS4552IPWT pin-compatible with any legacy Texas Instruments FDAs?
Yes, the THS4552IPWT is pin-compatible with the THS4522 in the 16-pin TSSOP (PW) package, enabling a direct upgrade path. Both share identical pinouts for IN1±, OUT1±, VOCM1, PD1, VS1±, and all Channel 2 equivalents. THS4552IPWT retains full functional compatibility while delivering 5 MHz higher bandwidth, 2.3 nV/√Hz lower noise, and improved HD3 performance versus THS4522.
