opa355, 2355, 3355 sbos195d 10 www.ti.com applications information the opa355 series is a cmos, high-speed, voltage-feed- back, operational amplifier designed for video and other general-purpose applications. it is available as a single, dual, or triple op amp. the amplifier features a 200mhz gain bandwidth and 360v/ s slew rate, but it is unity-gain stable and can be operated as a +1v/v voltage follower. its input common-mode voltage range includes ground, al- lowing the opa355 to be used in virtually any single-supply application up to a supply voltage of +5.5v. pcb layout good high-frequency pc board layout techniques should be employed for the opa355. generous use of ground planes, short direct signal traces, and a suitable bypass capacitor located at the v+ pin will assure clean, stable operation. large areas of copper also provide a means of dissipating heat that is generated within the amplifier in normal opera- tion. sockets are definitely not recommended for use with any high-speed amplifier. a 10nf ceramic bypass capacitor is the minimum recom- mended value; adding a 1 f or larger tantalum capacitor in typical characteristics (cont.) at t a = +25 c, v s = 5v, g = +2, r f = 604 ? , and r l = 150 ? connected to v s /2, unless otherwise noted. channel-to-channel crosstalk frequency (hz) crosstalk, input-referred (db) 10m 1m 100m 100k 0 20 40 60 80 100 120 opa3355 (triple) opa2355 (dual) parallel can be beneficial when driving a low-resistance load. providing adequate bypass capacitance is essential to achiev- ing very low harmonic and intermodulation distortion. operating voltage the opa355 is specified over a power-supply range of +2.7v to +5.5v ( 1.35v to 2.75v). however, the supply voltage may range from +2.5v to +5.5v ( 1.25v to 2.75v). supply voltages higher than 7.5v (absolute maximum) can perma- nently damage the amplifier. parameters that vary significantly over supply voltage or temperature are shown in the typical characteristics section of this data sheet. enable function the opa355 can be enabled by applying a ttl high voltage level to the enable pin. conversely, a ttl low voltage level will disable the amplifier, reducing its supply current from 8.3ma to only 3.4 a per amplifier. this pin voltage is referenced to single-supply ground. when using a split-supply, such as 2.5v, the enable/disable voltage levels will be referenced to v . independent enable pins are available for each channel, providing maximum design flex- ibility. for portable battery-operated applications, this feature can be used to greatly reduce the average current and thereby extend battery life.
opa355, 2355, 3355 sbos195d 11 www.ti.com the enable input can be modeled as a cmos input gate with a 100k ? pull-up resistor to v+. left open, the enable pin will assume a logic high, and the amplifier will be on. the enable time is 100ns and the disable time is only 30ns. this allows the opa355 to be operated as a gated amplifier, or to have its output multiplexed onto a common output bus. when disabled, the output assumes a high-impedance state. output drive the output stage can supply high short-circuit current (typi- cally over 200ma). therefore, an on-chip thermal shutdown circuit is provided to protect the opa355 from dangerously high junction temperatures. at 160 c, the protection circuit will shut down the amplifier. normal operation will resume when the junction temperature cools to below 140 c. note: it is not recommended to run a continuous dc current in excess of 60ma. refer to the typical characteristics, output voltage swing vs output current . video the opa355 output stage is capable of driving a standard back-terminated 75 ? video cable. by back-terminating a transmission line, it does not exhibit a capacitive load to its driver. a properly back-terminated 75 ? cable does not ap- pear as capacitance; it presents only a 150 ? resistive load to the opa355 output. the opa355 can be used as an amplifier for rgb graphic signals, which have a voltage of zero at the video black level, by offsetting and ac-coupling the signal, as shown in figure 1. wideband video multiplexing one common application for video speed amplifiers which include an enable pin is to wire multiple amplifier outputs together, then select which one of several possible video inputs to source onto a single line. this simple wired-or video multiplexer can be easily implemented using the opa357; see figure 2. input and esd protection all opa355 pins are static protected with internal esd protection diodes tied to the supplies; see figure 3. these diodes will provide overdrive protection if the current is externally limited to 10ma by the source or by a resistor. figure 1. rgb cable driver. 1/3 opa355 604 ? 1 f 10nf +3v 75 ? red green blue 604 ? r 2 r 1 red (1) v+ r 2 r 1 green (1) v+ r 2 r 1 blue (1) v+ 75 ? 220 f 604 ? 75 ? 75 ? 1/3 opa355 1/3 opa355 604 ? 75 ? 604 ? 604 ? 75 ? + note: (1) source video signal offset 300mv above ground to accommodate op amp swing-to-ground capability. 220 f 220 f
