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.
