What are the key features of THS1041IDWRG4?
- 10-bit resolution at 40 MSPS sampling rate delivers high-speed digitization with low power consumption for portable and embedded signal-capture designs
- Single-ended ±1 V analog input range with proprietary conversion method provides excellent linearity error of only 0.1465 % for accurate signal fidelity
- 28-pin SOIC package with single analog input channel simplifies PCB layout and reduces noise coupling compared to multi-channel monolithic ADC solutions
What is THS1041IDWRG4 used for?
The THS1041IDWRG4 is suited for portable data acquisition systems, software-defined radio front ends, and medical ultrasound signal digitization where a 10-bit, 40 MSPS conversion rate provides the right balance of dynamic range and speed. Its low-power architecture makes it attractive for battery-operated test instruments, handheld spectrum analyzers, and FPGA-based signal processing boards that digitize intermediate-frequency signals up to 20 MHz bandwidth. The ±1 V differential input range also fits directly with many RF mixer and IF amplifier output levels, minimizing the need for additional gain-scaling stages.

Frequently Asked Questions
What sampling rate and resolution does the THS1041IDWRG4 achieve, and what analog bandwidth does that support?
The THS1041IDWRG4 samples at 40 MSPS with 10-bit resolution, which by Nyquist's theorem supports analog input bandwidths up to 20 MHz without aliasing. This combination makes it well matched to intermediate-frequency signal chains in communications receivers, portable spectrum analyzers, and ultrasound systems where both speed and moderate dynamic range are required in a single-channel converter.
What is the analog input voltage range of the THS1041IDWRG4, and how does it connect to a typical RF IF signal chain?
The THS1041IDWRG4 accepts analog inputs from -1 V to +1 V, giving a 2 V peak-to-peak full-scale range. Most RF IF amplifiers and mixers produce outputs in the -1 V to +1 V range at standard 50-ohm impedance levels, so the converter can be driven directly through a simple impedance-matching network without a separate differential driver amplifier, reducing component count and board noise in compact receiver designs.
How does the THS1041IDWRG4 compare to a 12-bit ADC for software-defined radio designs requiring cost and power trade-offs?
For software-defined radio front ends operating below 30 MHz signal bandwidth, the THS1041IDWRG4 at 10 bits and 40 MSPS consumes significantly less power than a 12-bit, 40 MSPS counterpart such as the ADS807, while providing 60 dB theoretical dynamic range — sufficient for many narrowband AM, FM, and SSB demodulation tasks. Designers targeting 72 dB of spurious-free dynamic range and above should step up to 12-bit converters, but the THS1041IDWRG4 remains the lower-cost, lower-power choice for medium-precision applications.
What package does the THS1041IDWRG4 use, and how does it influence PCB layout for high-speed ADC signal integrity?
The THS1041IDWRG4 is housed in a 28-pin SOIC package with 1.27 mm pin pitch, which provides ample pad size for hand soldering or standard reflow processes. For 40 MSPS signal integrity, the SOIC lead inductance requires decoupling capacitors of 100 nF placed within 2 mm of each supply pin, and analog input traces should be kept under 25 mm to minimize parasitic capacitance that degrades effective number of bits at full sampling rate.
