Description

The PI5A100 is an improved Quad Single-pole double-throw (4SPDT) CMOS analog switch designed to operate with a single +2V to +6V power supply. The EN pin may be used to place all switches in a high-impedance state. This high precision device is ideal for low-distortion audio, video, and data switching and routing. Each switch conducts current equally well in either direction when on. In the off state each switch blocks voltages up to the power-supply rails. The PI5A100 is fully specified with +5V , and +3.3V supplies. With +5V , it guarantees less than 10Ω On-Resistance. On-Resistance matching between channels is within 2Ω. On-Resistance flatness is less than 4Ω over the specified range. The PI5A100 guarantees fast switching speeds (tON < 12ns). The PI5A100 is available in the narrow-body SOIC and QSOP packages for operation over the industrial (-40°C to +85°C) tem- perature range.

Precision, Wide-Bandwidth, Quad SPDT Analog Switch Applications Information Overvoltage Protection Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings may cause permanent damage to the devices. Always sequence V+ on first, followed by V-, and then logic inputs. If power-supply sequencing is not possible, add two small signal diodes or two current limiting resistors in series with the supply pins for overvoltage protection (Figure 8). Adding diodes reduces the analog signal range, but low switch resistance and low leakage characteristics are unaffected. RGB Switch Figure 9 illustrates a simple low cost RGB switch. The RGB - to-Composite Decoder produces either NTSC or S-VHS video from an RGB source. Asingle PI5A100 selects one of the two video sources to produce either SVHS, Composite or RGB video outputs. The low insertion loss of the PI5A100 eliminates the need for expensive input/output buffers. Figure 8: Overvoltage protection is accomplished using two ex- ternal blocking diodes or two current limiting resistors.

Precision, Wide-Bandwidth, Quad SPDT Analog Switch Figure 8 shows the PI5A100 in an audio card muting application. The original problem was one of excessive popping/clicking noise appearing when connecting disconnecting external loads, and at power on/off. The PI5A100 performs a muting function by grounding the outputs at power on/off and during the transition time. The 32Ω headset impedance demands a very low and very flat switch- on resistance to reduce THD and signal loss. Figure 10: The PI5A100 momentarily mutes the stereo outputs by connecting them to ground during transition times. Paralleling two sections of the PI5A100 produces a Ron of 2.5Ω with an unsurpassed ±0.5Ω flatness. To handle AC signals it was necessary to power the device with ±3V provided by two Zener diodes: Z1 and Z2. The select and Enable control signals are shifted by using twpo 2.5V Zener diodes Z3,Z4 and pull down resistors connected to -3V .
