Dual, 5 Analog Switches
General Description
The MAX4621/MAX4622/MAX4623 are precision, dual, high-speed analog switches. The single-pole/singlethrow (SPST) MAX4621 and double-pole/single-throw (DPST) MAX4623 dual switches are normally open (NO). The single-pole/double-throw (SPDT) MAX4622 has two normally closed (NC) and two NO poles. All three parts offer low 5 on-resistance guaranteed to match to within 0.5 between channels and to remain flat over the full analog signal range (0.5 max). They also offer low leakage (<500pA at +25C, <5nA at +85C) and fast switching times (turn-on time <250ns, turn-off time <200ns). These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automatic test equipment or applications where current switching is required. They have low power requirements, use less board space, and are more reliable than mechanical relays. The MAX4621/MAX4622/MAX4623 are pin-compatible replacements for the DG401/DG403/DG405, respectively, offering improved overall performance. These monolithic switches operate from a single positive supply (+4.5V to +36V) or with bipolar supplies (4.5V to 18V) while retaining CMOS-logic input compatibility.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value is a maximum, is used in this data sheet. Note 3: Guaranteed by design. Note 4: RON = RON_MAX - RON_MIN. Note 5: Flatness is defined as the difference between the maximum and minimum values of on-resistance as measured over the specified analog signal range. Note 6: Leakage currents are 100% tested at the maximum-rated hot temperature and guaranteed by correlation at +25C. Note 7: Off-isolation = 20log10 [VCOM_ / (VNC_ or VNO_)]. VCOM_ = output, VNC_ or VNO_ = input to off switch. Note 8: Between any two switches. Note 9: Leakage testing for single-supply operation is guaranteed by testing with dual supplies.

Operation with Supply Voltages Other than 15V
The MAX4621/MAX4622/MAX4623 switches operate with 4.5V to 18V bipolar supplies and a +4.5V to +36V single supply. In either case, analog signals ranging from V+ to V- can be switched. The Typical Operating Characteristics graphs show the typical on-resistance variation with analog signal and supply voltage.

Overvoltage Protection
Proper power-supply sequencing is recommended for all CMOS devices. It is important not to 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 VL, V-, and logic inputs. If power-supply sequencing is not possible, add two small signal diodes in series with the supply pins and a Schottky diode between V+ and VL (Figure 1). Adding diodes reduces the analog signal range to 1V below V+ and 1V above V-, but low switch resistance and low leakage characteristics are unaffected. The difference between V+ and V- should not exceed +44V.
