ADI ADG4612BRUZ-REEL7

The ADG4612/ADG4613 contain four independent single-pole single-throw (SPST) switches. The ADG4612 switches turn on when the relevant control input is Logic 1. The ADG4613 has two switches with digital control logic similar to the ADG4612, while the other two switches have inverted control logic. When on, each switch conducts equally in both directions, and the input signal range can extend to the supply voltage range. The ADG4613 is a break-before-make switch, suitable for multiplexer applications. When power is absent, the switches remain open and the switch inputs are high impedance, ensuring no current flows that could damage the switches or downstream circuitry. This feature is particularly useful in applications where analog signals may be present at the switch inputs before power is applied, or where the user cannot control the power supply sequencing. In the off condition, signal levels up to 16 V are blocked. In addition, if the analog input signal level exceeds VDD by VT, the switch will turn off. These switches feature low on-resistance, making them ideal for data acquisition and gain switching applications where low on-resistance and low distortion performance are critical. The on-resistance profile is extremely flat across the entire analog input range, ensuring excellent linearity and low distortion when switching audio signals.
