SiT6098EBB Evaluation Board Introduction
The SiT6098EBB evaluation board provides the ability to evaluate the functionality of the 32 kHz
oscillators on a simple board that makes it easy to power up the oscillator and observe the output
buffered through an operational amplifier. The analog buffer isolates the device from the significant
loading, which is important for performing best waveform and current measurements.
The SiT6098EBB supports the following package size: 1.5 x 0.8 mm CSP
