Product Details
●TThe ADG774A is a monolithic CMOS device comprising four 2:1 multiplexer/demultiplexers with high impedance outputs. The CMOS process provides low power dissipation yet offers high switching speed and low on resistance. The on resistance variation is typically less than 0.5 Ω over the input signal range.
●The bandwidth of the ADG774A is typically 400 MHz and this, coupled with low distortion (typically 0.3%), makes the part suitable for switching of high speed data signals.
●The on resistance profile is very flat over the full analog input range ensuring excellent linearity and low distortion. CMOS construction ensures ultralow power dissipation.
●The ADG774A operates from a single 3.3 V/5 V supply and is TTL logic-compatible. The control logic for each switch is shown in the truth table.
●These switches conduct equally well in both directions when on. In the off condition, signal levels up to the supplies are blocked. The ADG774A switches exhibit break-before-make switching action.
●Product Highlights
● 1. Wide bandwidth data rates of >400 MHz.
● 2. Ultralow power dissipation.
● 3. Low leakage over temperature.
● 4. Break-before-make switching prevents channel shorting when the switches are configured as a multiplexer.
● 5. Crosstalk is typically −70 dB @ 10 MHz.
● 6. Off isolation is typically −65 dB @ 10 MHz.
● 7. Available in compact 3 mm × 3 mm LFCSP.
