TDA7521
8/11
Notes: 1. Current or Voltage input, DC coupled
2. Precision Resistor connected between Rext and ground
3. These pins are to be left unconnected
4. Internally generated, need external filter ing cap
5. Buffered Vcc/2 Output
6. Driven by IC6D, active high
7. Dirven by IC6D, active low
8. 1 Vrms max., VCC/2 DC component
9. Needs RC-C externals network
10.High in correspondence of the HF sample preceding the AC one
11.LSB+1 of the HF ADC, Underflow bit of the servo one
12.LSB of the HF ADC, Overflow bit of the servo one
13.Can be selected among HF, AC, BD, E, F (via control interface)
14.Bidirectional, needs a pull-up resistor to 5 V line
15.Drives an external pnp.
