NJU7312A

The NJU7312A is a quad 3-channel and dual 2-channel analog function switch, especially  suitable for input selector of audio equipments.The high break down voltage analog switch controlled by 14-bit serial data based on logic operating voltage(5V) can ON and OFF of±15V signal.The analog switch is realized superior linearity of on-resistance in all voltage range, low distortion and wide dynamic range.Furthermore,the both of single and dual power supply application provides easy designing.

Features of the NJU7312A are:(1)analog switch:quad 3 channel and dual 2 channel; (2)high break down voltage:±15V; (3)low distortion:THD: 0.002% (typ); (4)superior linearity of ON resistance; (5)serial data control; (6)package outline:SDIP 28/DMP 30; (7)C-MOS technology.The serial input data is input to internal shift register sequentially synchronized by clock signal rising edge input from CK terminal (100 kHz max).The serial  input data in  the  shift  register  is transferred to latch circuit and renew by synchronized rising edge of chip enable signal input from ST terminal.

The absolute maximum ratings of the NJU7312A can be summarized as:(1)supply voltage:34V;(2)storage temperature:-40 to +125;(3)operating temperature:-30 to 75 ;(4)input voltage:Vss-0.3 to Vdd+0.3V;(5)power dissipation:300mW.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
