| ZXFBF05 4 Channel Buffer Device with high capacitance load capability DEVICE DESCRIPTION The ZXFBF05 is a low cost, high slew rate, quad buffer amplifier. Built using the Zetex CA700 technology, this buffer has a small signal bandwidth of greater than 100MHz and a 1 volt pk-pk bandwidth of greater than 20 MHz. Each channel draws only 7.5mA. The device operates from a 5 volt supply, which makes it ideal in a majority of applications. This space saving buffer may be used in a wide variety of applications such as, video switching matrix, multi-channel instrumentation equipment, and A/D input buffer, etc. FEATURES AND BENEFITS * * * * * * * * 4 Buffers per package Low distortion Class A O/P 100MHz bandwidth Low cost Designed for up to 300pF load Low supply current (7.5mA per buffer) No thermal runaway 14 pin SOIC package APPLICATIONS * * * * Video Switching Matrix input buffer Instrumentation Multi-channel A/D input buffer Multi-isolation buffer PART NUMBER ZXFBF05N14 PACKAGE SOIC14N PART MARK ZXFBF05 ORDERING INFORMATION PART NUMBER ZXFBF05N14TA ZXFBF05N14TC CONTAINER Reel 7" Reel 13" INCREMENT 500 2500 RELATED PRODUCTS ZXFBF04 4 Channel Buffer ZXFBF08 8 Channel Buffer ZXFBF25 4 Channel Buffer with output enable CONNECTION DIAGRAM OUT1 NC IN1 V+ IN2 NC OUT2 OUT4 NC IN4 VIN3 NC OUT3 14 PIN SOIC PACKAGE ISSUE 1 - FEBRUARY 2001 1 ZXFBF05 ABSOLUTE MAXIMUM RATINGS Voltage on any pin Operating temperature range Storage Temperature 20V (relative to V-) 0 to 70C (de-rated for -40 to 85C) -55 to 125C ELECTRICAL CHARACTERISTICS Test Conditions: Temperature =25C, V+ = 5.00, V- = -5.00V, RL = 1k, CL = 10pF Parameter Offset Voltage Offset Voltage Drift Supply Current Input Bias Current Output Voltage DC Gain DC Gain Sink Current Source Current Input Resistance Output Resistance Bandwidth Slew Rate Voltage Noise Differential Gain NTSC Differential Phase NTSC Differential Gain PAL Differential Phase PAL Channel Isolation 10 - 100 kHz F = 3.58MHz, V in = 0.286Vp-p, DC V in = 0 to 0.714V 20mVp-p, 1.0Vp-p Conditions V in = 0V V in = 0V All inputs = 0V V in = 0V R L = 200 V in = 0.5V, R L = 1k V offset = 0.0V V in = 0.5V, R L = 1k V offset = 0.25V V in = 0V, V out =0.5V V in = 0V, V out =-0.5V 0.95 0.95 4.0 8.0 10 5 5.0 0.1 Min. -25 Typical 20 30 1.0 1 0.98 0.98 6.0 15.0 20 10 100 20 40 15 0.1 0.15 0.1 F = 4.43MHz, V in = 0.286Vp-p, DC V in = 0 to 0.714V V in = 370mVp-p, RL = 1k F = 4 MHz 0.15 -60 1.00 1.00 12.0 18.0 100 15 40 2.0 Max. 25 Units mV V/C mA A V V/V V/V mA mA M MHz V/s nV/ Hz % Degrees % Degrees dB NOTES Test circuit for measuring channel isolation.
