Product details
Overview
THS1041CPWR from Texas Instruments is a 10-bit, 40 MSPS analog-to-digital converter (ADC) operating from a single 3-V supply. It supports configurable analog inputs (single-ended or differential), integrates a 3-bit programmable gain amplifier (PGA), and features an on-chip clamp circuit with 10-bit DAC for DC restoration-enabling direct use in video signal digitization and CCD imaging systems.
For engineers reviewing the THS1041CPWR datasheet, THS1041CPWR pinout, THS1041CPWR application, or THS1041CPWR equivalent, key selection considerations include its 40 MSPS sampling rate, ±0.45 LSB DNL, 72 dB SFDR at 4.8 MHz, dual-reference flexibility (internal/external), and TSSOP-28 package compatibility with high-density video acquisition layouts.
Technical Context
The THS1041CPWR implements a switched-capacitor sample-and-hold followed by a PGA and successive-approximation ADC core. Its reference architecture supports three MODE configurations: external REFT/REFB sourcing (MODE = AGND), internal buffered AVDD/2 (MODE = AVDD/2), or internal AVDD/2 with CLAMPOUT bias (MODE = AVDD).
Clamp functionality operates via CLAMPIN (external analog level) or internal 10-bit DAC (controlled via CLAMP register), with CLAMPOUT providing DC restoration or bias voltage. Digital interface uses parallel 10-bit I/O (I/O0–I/O9), WR strobe, OE control, and OVR out-of-range flag-supporting unsigned binary or 2's complement output formats.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - delivers 1024 distinct digital codes for precise amplitude quantization in imaging and communications signals. |
| Sampling Rate | 40 MSPS - enables real-time digitization of baseband video (e.g., NTSC/PAL) and high-speed CCD outputs without undersampling. |
| Differential Nonlinearity | ±0.45 LSB - ensures monotonicity and minimizes code-width variation critical for accurate histogram-based image processing. |
| Spurious-Free Dynamic Range | 72 dB at 4.8 MHz - suppresses harmonics and spurs to preserve signal integrity in demanding RF-adjacent or mixed-signal environments. |
| Signal-to-Noise Ratio | 60 dB typical at 4.8 MHz - supports >9-bit effective resolution for low-noise medical imaging and precision instrumentation. |
| PGA Gain Range | 0.5× to 4× in 8 linear steps - maintains SNR across small-signal CCD outputs while avoiding ADC saturation on large transients. |
| Operating Temperature | 0°C to 70°C - qualified for commercial-grade set-top-box, multimedia, and industrial embedded video capture applications. |
Pinout & Package
THS1041CPWR is housed in a 28-pin TSSOP (PW) package with 0.65 mm pitch, optimized for compact PCB layout and thermal performance in video front-end designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN+, AIN− | Differential analog input pair | Accepts ±1 Vpp or ±0.5 Vpp differential signals; supports ac-coupled video with CLAMPOUT-driven DC restoration. |
| VREF, REFT, REFB | Reference voltage interface | VREF selects internal 0.5 V or 1 V bandgap; REFT/REFB define full-scale range (e.g., 1 Vpp differential) when MODE = AVDD/2. |
| CLAMP, CLAMPIN, CLAMPOUT | DC restoration control path | CLAMP enables clamp mode; CLAMPIN accepts external clamp level; CLAMPOUT drives AIN+ or AIN− to restore DC bias. |
| I/O0–I/O9 | Parallel 10-bit digital output bus | Delivers conversion result on 4th CLK edge; supports 3-state operation via OE for shared data bus interfacing. |
| CLK, WR, OE, OVR | Timing and control interface | CLK synchronizes sampling; WR latches control registers; OE enables/disables outputs; OVR flags out-of-range conditions. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable input topology | Single-ended (with analog/digital clamp) or differential input - simplifies integration across diverse signal sources without external op-amps. |
| Integrated 10-bit clamp DAC | Programmable clamp level with ±40 mV error - eliminates need for external DAC and precision resistors in video DC restoration circuits. |
| Adjustable internal voltage reference | Selectable 0.5 V or 1 V internal reference (via REFSENSE) - reduces BOM count and improves temperature stability vs. external references. |
| Power-down mode | 75 µW standby power - enables rapid wake-up (45 µs) and dynamic power gating in battery-powered or thermally constrained imaging modules. |
| Out-of-range indicator | OVR pin asserts high on overrange - provides immediate hardware-level fault detection for automatic gain adjustment or signal clipping logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit, 40 MSPS ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS1000IRUGR | 12-bit, 1 MSPS, I²C interface, no PGA or clamp - lower speed, higher resolution, serial output. | Suitable for low-speed sensor monitoring; lacks video-rate sampling and analog conditioning features. | Choose THS1041CPWR for video/CCD; ADS1000IRUGR only for slow, precision sensor readout. |
| MAX1186ETL+ | 10-bit, 40 MSPS, but requires ±5 V supplies and separate analog/digital grounds - no single 3-V operation. | Compatible with legacy industrial systems using dual-rail supplies; incompatible with modern 3-V embedded video platforms. | THS1041CPWR enables simpler power design and smaller footprint where 3-V operation is mandatory. |
Compared with ADS1000IRUGR and MAX1186ETL+, the THS1041CPWR uniquely combines 40 MSPS speed, single 3-V supply, integrated clamp, and PGA in TSSOP-28-making it the only drop-in solution for space-constrained, low-power video digitization without redesigning power or signal conditioning.

FAQ
What is the maximum sampling frequency supported by the THS1041CPWR?
The THS1041CPWR supports a maximum sampling frequency of 40 MSPS under recommended operating conditions (AVDD = DVDD = 3 V, fCLK = 40 MHz). Performance metrics-including 72 dB SFDR and 60 dB SNR-are specified at this rate with a 4.8 MHz input tone, confirming full-rated operation without degradation.
Does the THS1041CPWR require external reference components?
No-the THS1041CPWR includes an adjustable internal voltage reference (0.5 V or 1 V) selectable via REFSENSE, eliminating the need for external references in most applications. External references are optional when higher accuracy or temperature stability is required, enabled by setting MODE = AGND and driving REFT/REFB externally.
How does the clamp function operate in the THS1041CPWR?
The THS1041CPWR clamp function restores DC bias on AC-coupled inputs using either an external voltage on CLAMPIN or an internal 10-bit DAC output on CLAMPOUT. When CLAMP = high, CLAMPOUT drives AIN+ or AIN− to the selected level-enabling seamless integration into video signal chains without external clamping circuitry.
What digital output format options does the THS1041CPWR support?
The THS1041CPWR supports both unsigned binary and 2's complement output formats, configured via internal control registers written through the WR strobe and I/O bus. This allows direct compatibility with FPGA logic expecting positive-only values or DSP cores requiring signed arithmetic without external translation logic.
Is the THS1041CPWR pin-compatible with other members of the THS1041 family?
Yes-the THS1041CPWR shares identical pinout and functionality with THS1041CDW (SOIC-28) and THS1041IPWR (industrial-temp TSSOP-28). All variants use the same 28-pin layout, register map, and timing specifications, enabling drop-in replacement across commercial and extended temperature grades when mechanical constraints permit.
