The full-scale output of about 2.0 VP-P is available by setting RL and Rref to 75 Ω and 768 Ω, respectively. An output impedance of the analog output terminal is almost the same as the load resistor (RL). NOTES TO THE OPERATION 1. Both a ground and a supply planes in a PCB should be as wide as possible for reducing a parasitic inductance and resistance. Especially, for the better performance, the analog plane needs to be much wider. 2. A tantalum or electrolytic capacitor of 10µF or more and a ceramic capacitor of 0.01µF are tied together, which are connected between a digital supply and ground, also between a analog supply and ground. These capacitors should be placed as close as possible to the IC. They work as bypass capacitors for preventing a degradation in the performance by a supply voltage fluctuation caused by digital signals including a clock and digital inputs and so on. 3. The analog output should be isolated as much as possible from a clock and digital inputs, thus minimizing decoupling and interactive noise. 6 MITSUBISHI ICs (AV COMMON) M65530FP TRIPLE 10-BIT VIDEO D-A CONVERTER APPLICATION EXAMPLE 68 67 66 65 64 63 62 61 60 59 58 57 56 55 R0 1 R0(LSB) R1 2 R1 VG1’B 53 AVSS 54 R2 3 R2 VG1B 52 R3 4 R3 VG1’G 51 R4 5 R4 VG1G 50 R5 6 R5 VG1’R 49 R6 7 R6 VG1R 48 R7 8 R7 VGB 47 R8 9 R8 VGG 46 R9 10 R9 G0 11 G0(LSB) lrefB 44 750Ω G1 12 G1 lrefG 43 750Ω G2 13 G2 lrefR 42 750Ω G3 14 G3 AVSS 41 G4 15 G4 VG2 40 G5 16 G5 DVSS 39 G6 17 G6 18 G7 CLKB 38 CLKB G7 CLKG 37 CLKG G8 19 G8 CLKR 36 CLKR M65530FP 20 N.C 0.01µ 0.01µ 0.01µ 0.01µ VGR 45 0.01µ N.C 35 21 22 23 24 25 26 27 28 29 30 31 32 33 34 Units Resistance : Ω Capacitance : F Digital power supply Digital GND Analog power supply Analog GND 7
