Frequently Asked Questions
What resolution and linearity does PCM1750UG4 provide for professional audio digitization?
PCM1750UG4 delivers 18-bit resolution with a maximum linearity error of 0.003%, making it suitable for professional studio recording and high-fidelity playback systems. At 18-bit depth, dynamic range exceeds 100 dB, allowing the capture of subtle audio nuances that lower-resolution converters would miss. The low 0.003% linearity error ensures faithful amplitude reproduction across the ±2.75V input range.
How does PCM1750UG4 handle simultaneous dual-channel sampling for stereo applications?
PCM1750UG4 provides 2 analog input channels that sample simultaneously, preserving the phase relationship between left and right audio signals in stereo recordings. This simultaneous capture eliminates interchannel skew errors that can degrade stereo imaging in music production and broadcast workflows. The 20.8 µs maximum conversion time corresponds to a sampling capability well above 20 kHz audio bandwidth requirements.
What supply voltages does PCM1750UG4 require, and is it still in production?
PCM1750UG4 operates with a nominal negative supply of -5V alongside a positive supply, making it a dual-supply device requiring a bipolar power rail. The part is marked with YTEOL 0, indicating it is at or near end-of-life status, so designers starting new projects should evaluate current TI audio ADC alternatives. Existing inventory may still be available through distribution channels with worldwide shipping.
For which audio and measurement applications is PCM1750UG4 most applicable?
PCM1750UG4 fits digital mixing consoles, professional tape or disk recorders, and precision sound-level measurement instruments where 18-bit accuracy and dual-channel simultaneous conversion are needed. Its ±2.75V analog input range directly accepts balanced line-level signals without an additional attenuator stage. Medical audiometry equipment and broadcast satellite ground stations also use this device for its low linearity error of 0.003%.
