Frequently Asked Questions
What is the sampling rate and resolution of TLV990-21PFBG4?
The TLV990-21PFBG4 delivers 10-bit resolution at a sampling rate of 21,000 ksps (21 Msps). This combination makes it suitable for mid-speed analogue front-end applications such as digital oscilloscopes, communications receivers, and medical imaging systems that require accurate signal capture across a wide frequency band.
How does the 48-pin TQFP package of TLV990-21PFBG4 affect thermal management on the PCB?
The TLV990-21PFBG4 uses a 48-pin TQFP package (JESD-30 S-PQFP-G48) with a plastic/epoxy body in a thin fine-pitch flatpack style that includes an integrated heat sink slug. This slug allows designers to solder it directly to a thermal pad on the PCB, improving heat dissipation when operating at the 260°C peak reflow temperature and supporting continuous high-speed 21 Msps operation in compact system designs.
Which serial interface does TLV990-21PFBG4 use and how does it simplify system integration?
The TLV990-21PFBG4 uses a 3-wire serial interface for digital output, which reduces pin count compared to parallel-output ADCs and simplifies board routing on 48-pin TQFP-based designs. A single function channel with 10-bit data over 3 wires integrates easily with SPI-compatible FPGAs or DSPs, lowering firmware complexity and shortening development cycles for imaging and instrumentation front-end boards.
