Features

• REC equalizer is very small number of external parts, built-in 2 types of frequency characteristics.
• PB equalizer circuit built-in.
• REC /PB of high speed mode are possible with TYPE 1(Normal tape).
• Controllable from direct micro-computer output.
• Available to reduce substrate-area because of high integration and small external parts.
• As the pins arrangement resembles HA12185NT, it can design the board that is replaced with HA12185NT. HA12207NT Pin Description, Equivalent Circuit (VCC = 10.5V, Vref = 5.6V, Ta = 25°C, No signal, The value in the table show typical value.) Pin No. 1 2.
