NJM2267

The NJM2267 is a kind of dual video 6 dB amplifier with 75 drivers for SVHS VCRs, HI-BAND, VCRs. Each channel has clamp function that fixes DC level of video signal and 75 drivers to be connected to TV monitors directly. It has sag corrective circuits that prevent the generation of sag with smaller capacitance than ever. Its operating supply voltage is from 4.85 to 9 V and bandwidth is 7 MHz.

There are some features as follows: (1)wide operating voltage: 4.85 to 9.0 V; (2)dual channel; (3)internal clamp function; (4)internal driver circuit for 75 load; (5)SAG corrective function; (6)wide frequency range (7 MHz); (7)low operating current: 14.0 mA dual; (8)package outline: DIP8, DMP8 and SSOP8; (9)bipolar technology.

What comes next is about the absolute maximum ratings: (1)supply voltage, V+: 10 V; (2)power dissipation, PD: 500 mW (DIP), 300 mW (DMP8) and 250 mW (SSOP); (3)operating temperature, Topr: -40 to +85; (4)storage temperature, Tstg: -40 to +125. Then is about the electrical characteristics: (1)operating current, ICC: 14.0 mA typ and 18.2 dB max when no signal; (2)voltage gain, GV: 5.7 dB min, 6.2 dB typ and 6.7 dB max at VIN=1 MHz, 1 VP-P sinewave; (3)frequency characteristic, Gr: ±1.0 dB max at VIN=1 VP-P, sinewave, 7 MHz/1 MHz; (4)differential gain, DG: 1.0% typ and 3.0% max at VIN=1 VP-P, staircase; (5)differential phase, DP: 1.0% typ and 3.0% max at VIN=1 VP-P, staircase; (6)crosstalk, CT: -70 dB typ at VIN=4.43 MHz, 1 VP-P, sinewave; (7)gain offset, GCH: ±0.5 dB at VIN=1 MHz, 1 VP-P, GCH=VOUT1-VOUT2; (8)input clamp voltage, VCL: 1.79 V min, 1.91 V typ and 2.03 V max; (9)SAG terminal gain, GSAG: 35 dB min and 45 dB typ.
