meist auch deutlich höhere Bandbreiten haben. Geeignete bzw. passende Typen wären beispielsweise: MCP6022 (Rail-to-Rail, 2,8 MHz, 7 V/µs, allerdings max. 6 V Versorgung → nicht geeignet für ±15 V) OPA197 – passt sehr gut: Versorgung: ±2,25 V bis ±18 V Rail-to-Rail-Ausgang GBW: 10 MHz Slew Rate: 20 V
achievable with an the voltage level of AIN is equal to or less than operational amplifier, such as the MCP6022, which has VSS + 1/2 LSB, the resultant code will be 000h. Addi- a closed-loop output impedance of tens of ohms. tionally, if the voltage at AIN is equal to or greater than VDD - 1.5 LSB, the output
specific to read later, the PIC18F2520 measures the high pulse to compassing are the 2x8 LCD, and the MCP6022/ determine the angle. The MXD2020EL has a tempera- MCP6024 operational amplifiers. The MOSFET ture output that is connected to AN3 on the responsible for creating the Set/Reset pulse is an PIC18F2520
