The LD3502 series provides high performance read/write preamplifiers for use in digital video cameras (DVCs). It provides write current control, data protection circuitry and a low noise read preamplifier for two channels. Data protection is provided so that during power supply sequencing the write current generator is disabled. System write-to-read recovery time is minimized by maintaining the read channel common-mode output voltage in write mode. Very low power dissipation is achieved with a single supply, BiCMOS processing and innovative circuit design techniques in the 5V write circuitry. When idle, the device enters a Sleep mode in which power dissipation is reduced to less than 3mW. The LD3502 series is packaged as a 14 pin TSSOP.
