Hello, Please ask a question about TSV782IYST Datasheet
# Example questions:
➢ What is the typical input offset voltage at vcc = 2v, and how does it change with temperature based on the provided datasheet?
➢ Compare the slew rate at vcc = 5v and vcc = 2v. what factors might contribute to the difference?
➢ What is the typical total harmonic distortion plus noise (thd+n) at 1khz with a 10kω load, and what does this indicate about the signal quality?
Important Notes & Considerations:
️· Supply Voltage (Vcc): The data sheets present specs at *both* 5V and 2V supply voltages. Pay very close attention to this as performance changes significantly.
️· Typical vs. Guaranteed: The tables specify “Min,” “Typ,” and “Max” values. “Typ” values are typical performance based on testing, but are *not* guaranteed in production. “Min” and “Max” are the guaranteed limits. The last pages contain typical performance graphs which give more information.
️· Load Conditions: Many parameters are tested with a specific load resistance (RL) and capacitance (CL) - typically RL = 10kΩ and CL = 47pF.
️· Two sets of data: There are slight variations between the first three pages and the following pages. The last set of pages present data at 5V and 2V, but also include some additional tests and graphs.
️· Overload Recovery Time: There is a discrepancy for this spec: 200ns versus 250ns
️· Slew Rate: There is a discrepancy for this spec: 13-17 V/us versus 17-23 V/us
️· THD+N: There is a discrepancy for this spec: 0.004% versus 0.005%
