Product details
Overview
THS7375IPWR from Texas Instruments is a 4-channel SDTV video amplifier with integrated sixth-order 9.5-MHz Butterworth low-pass filters, 5.6-V/V (14.95 dB) fixed gain, rail-to-rail output stage, and support for CVBS, S-video, Y'P'BP'R, Y'U'V', and G'B'R' signals. It operates from +3 V to +5 V single supply and delivers <0.2% differential gain / 0.35° differential phase error for NTSC/PAL systems in set-top boxes and DaVinci™-based video buffering.
For engineers reviewing the THS7375IPWR datasheet, THS7375IPWR pinout, THS7375IPWR application, or THS7375IPWR equivalent, key selection criteria include its 9.5-MHz filter bandwidth, 75-Ω line driving capability per channel, 9.8-mA quiescent current at 3.3 V, disable/bypass logic control, and TSSOP-14 package compatibility with space-constrained video signal chains.
Technical Context
The THS7375IPWR integrates four independent video amplifiers, each with a configurable sixth-order Butterworth filter (–3 dB at 9.5 MHz, –1 dB passband at 8 MHz, 54-dB attenuation at 27 MHz) that can be bypassed via dedicated logic input. Input biasing supports DC-coupled operation with 320-mV level shift or AC-coupled modes with sync-tip clamp for CVBS/Y'/G'B'R' signals.
Its rail-to-rail output stage drives 75-Ω or 150-Ω loads directly, supporting both AC and DC coupling. The device features separate DISABLE and BYPASS pins with TTL-compatible thresholds, enabling dynamic power management and real-time filter engagement without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 4 independent video amplifiers for CVBS/S-video/Y'P'BP'R/G'B'R' |
| Filter Bandwidth | 9.5-MHz sixth-order Butterworth LPF (–3 dB); bypassable for wideband operation up to 70 MHz |
| Gain | Fixed 5.6-V/V (14.95 dB); eliminates need for external gain-setting resistors |
| Supply Range | +3 V to +5 V single supply; supports portable and USB-powered designs |
| Quiescent Current | 9.8 mA at 3.3 V; drops to 0.1 mA in disabled state for power-sensitive applications |

| Output Drive | Rail-to-rail swing within 100 mV of rails; drives two 75-Ω lines per channel simultaneously |
Pinout & Package
TSSOP-14 package (4.4 mm × 5.0 mm, 0.65 mm pitch), lead-free and RoHS-compliant, optimized for high-density PCB layouts in consumer video equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CH1 IN – CH4 IN (Pins 1–4) | Video input terminals | Accept baseband analog video signals; support DC-coupled (320-mV shift) or AC-coupled (sync-tip clamp) biasing |
| GND (Pin 5) | Ground reference | Common return for all internal circuitry and output loads |
| DISABLE (Pin 6) | Enable/disable control | Logic-high disables amplifier (IQ ≤ 0.1 mA); must be tied to GND or VS+ - no floating |
| NC (Pins 7, 8) | No connection | Not internally bonded; leave unconnected |
| BYPASS (Pin 9) | Filter mode selector | Logic-high bypasses internal LPF; logic-low engages 9.5-MHz filter - enables runtime reconfiguration |

| CH4 OUT – CH1 OUT (Pins 11–14) | Video output terminals | Rail-to-rail outputs drive 75-Ω coaxial cables directly; support AC or DC coupling |
Key Features
| Feature | Design Value |

IC Role / Device Role / Timing Role: Four-channel line driver with 75-Ω impedance matching and low crosstalk (<–55 dB). Use Value: Maintains signal integrity across 100+ meter RG-59 runs; differential phase error <0.35° prevents color smearing in surveillance footage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS7354IPW | 3-channel version; identical 9.5-MHz filter, gain, and TSSOP-14 package; lacks CH4 channel | Used where only three video paths (e.g., CVBS + Y/C + RGB) are required | Select when fourth channel is unnecessary to reduce cost and board area |
| LMH6738MA | Single-channel, wideband (250-MHz GBW), no integrated filter; requires external passive LPF for SDTV compliance | Preferred for high-fidelity test equipment or multi-standard video where filter customization is needed | Choose when design requires >100-MHz bandwidth or programmable filter cutoff beyond 9.5 MHz |
Compared with THS7375IPWR, THS7354IPW offers identical performance per channel but omits the fourth amplifier, while LMH6738MA provides higher bandwidth at the cost of added external filtering complexity and no built-in SDTV-optimized LPF.

FAQ
What video standards does the THS7375IPWR support?
The THS7375IPWR supports CVBS, S-video, Y'P'BP'R (480i/576i), Y'U'V', and G'B'R' (R'G'B') SDTV standards. Its 9.5-MHz sixth-order Butterworth filter and <0.2%/0.35° differential gain/phase error meet NTSC and PAL broadcast requirements. The device is explicitly validated for use in DaVinci™-based video pipelines and SCART interfaces per TI SBOS449A documentation.
Can the THS7375IPWR drive 75-Ω coaxial cables directly?
Yes, the THS7375IPWR is designed to drive 75-Ω loads directly. Each channel delivers rail-to-rail output swing within 100 mV of the supply rails and supports driving two 75-Ω lines simultaneously. Output impedance is 1.4 Ω at 5 MHz in filter mode, ensuring minimal signal reflection and maintaining SDTV signal integrity without external termination or buffer stages.
How does the BYPASS pin affect THS7375IPWR operation?
The BYPASS pin on the THS7375IPWR controls engagement of the internal sixth-order 9.5-MHz low-pass filter. When pulled high (≥2.1 V at 5 V supply), the filter is bypassed, enabling wideband operation up to 70 MHz. When low (≤0.8 V), the filter is active. Switching occurs in 5 ns, allowing real-time reconfiguration - critical for debugging (bypassed) vs. production (filtered) modes in DaVinci™ systems.
What is the minimum supply voltage for reliable THS7375IPWR operation?
The THS7375IPWR operates reliably down to +2.85 V across temperature (–40°C to +85°C), though its specified minimum operating voltage is +3 V. At 2.85 V, parameters such as quiescent current (min 6.5 mA), output swing, and filter response remain functional per TI characterization data. For guaranteed specification compliance per SBOS449A, +3 V is the recommended lower limit.
Is the THS7375IPWR pin-compatible with other devices in the THS73xx family?
The THS7375IPWR shares the same TSSOP-14 pinout as THS7354IPW (3-channel) and THS7373IPW (4-channel with different gain), enabling layout reuse across variants. Pin functions - including CHx IN/OUT, DISABLE, BYPASS, VS+, and GND - are identical. However, THS7375IPWR's fixed 5.6-V/V gain and 9.5-MHz filter are unique; substituting other family members requires verification of gain, filter, and channel count alignment with system requirements.
