NJM2235

The NJM2235 is a kind of 3-input video switch for video and audio signal. It has clamp function and so is applied to fixed DC level of video signal. Its operating supply voltage range is from 5 to 12 V and bandwidth is 10 MHz. Crosstalk is 70 dB (at 4.43 MHz). The NJM2235 applications include VCR, video camera AV-TV, video disc player.

There are some features of NJM2235 as follows: (1)operating voltage: +4.75 to +13 V; (2)3 input-output; (3)internal clamp function; (4)wide operating supply voltage range: 4.75 to 13 V; (5)crosstalk: 70 dB (at 4.43 MHz); (6)wide frequency range: 10 MHz; (7)muting function available; (8)package outline: DIP-8, DMP-8, SIP-8, SSOP-8; (9)bipolar technology.

The following is about the absolute maximum ratings of NJM2235: (1)supply voltage, V+: 15 V; (2)power dissipation, PD: 500 mW (DIP8), 300 mW (SMP8), 250 mW (SSOP8) and 800 mW (SIP8); (3)operating temperature, Topr: -20 to +75; (4)storage temperature range, Tstg: -40 to +125.

The last one is about the electrical characteristics of NJM2235: (1)recommended supply voltage, V+: 4.75 to 13 V; (2)operating current, ICC: 10.5 mA typ and 14.0 mA max at S1=S2=S3=S4=S5=1; (3)voltage gain, GV: -0.5 dB min and +0.5 dB max at Vi=2.5 Vpp, 100 kHz VO/Vi; (4)differential gain, DG: 0% typ at Vi=2VPP staircase signal; (5)differential phase, DP: 0 deg typ at Vi=2VPP staircase signal; (6)output offset voltage, Voff: -30 V min, 0 V typ and +30 V max; (7)input clamp voltage, VIC: 2.0 V typ ; (8)output impedance, RO: 10 typ.
