6 / 8 page CMD6392 4-Channel BTL Driver for Players * All specs and applications shown above subject to change without prior notice. 1F-5 NO.66 SEC.2 NAN-KAN RD ., LUCHU , TAOYUAN, TAIWAN Email: server@ceramate.com.tw Tel:886-3-3214525 Http: www.ceramate.com.tw Fax:886-3-3521052 Page 6 of 8 Rev 1.2 Oct.24, 2002 This can be increased by inserting a capacitor between point A (pins 3, 11 and 18) and VREF. The constant current (Iconst) given in the electrical characteristics refers to I1 and I2 in Fig. 2. (2) CH4 driver (spindle driver) Pins 23 and 25 are shorted inside the IC. Bias amplitudes are the primary type of inputs assumed. The level shift circuit converts the pre-stage amplifier output (centered on the bias level and impressed on pins 23 and 25) to positive and negative amplitudes centered on VREF. The level shift circuit’s output is BTL-output from the buffer amplifier. Because of the high input impedance, the IC is designed to accommodate a filter comprising attached resistors and capacitors. FOperation notes (1) The CM D6392FP has an internal thermal shutdown circuit. Output current is muted when the chip tempera- ture exceeds 180 _C (typically). (2) The output current can also be muted by lowering the mute pin (pin 15) voltage below 0.5V. (3) All four driver output channels are muted during thermal shutdown, muting and a drop in bias pin voltage. No other components are muted. (Example) For secondary filters |
