Improved, Dual, High-Speed Analog Switches

_______________General Description

Maxim's redesigned DG401/DG403/DG405 analog switches now feature guaranteed low on-resistance matching between switches (2Ω max) and guaranteed on-resistance flatness over the signal range (3Ω max). These low on-resistance switches (20Ω typ) conduct equally well in either direction and are guaranteed to have low charge injection (15pC max). The new design offers lower off leakage current over temperature (less than 5nA at +85°C).

The DG401/DG403/DG405 are dual, high-speed switches. The single-pole/single-throw DG401 and double-pole/single-throw DG405 are normally open dual switches. The dual, single-pole/double-throw DG403 has two normally open and two normally closed switches. Switching times are 150ns max for tON and 100ns max for tOFF, with a maximum power consumption of 35µW. These devices operate from a single +10V to +30V supply, or bipolar supplies of ±4.5V to ±20V. Maxim's improved DG401/DG403/DG405 are fabricated with a 44V silicon-gate process.

Note 1: Signals on S, D or IN exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current rating.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: This data sheet uses the algebraic convention, where the most negative value is a minimum and the most positive value is a maximum.

Note 3: Guaranteed by design.

Note 4: ∆ rON = ∆ rON(max) - ∆ rON(min). On-resistance match between channels and flatness are guaranteed only with specified voltages. Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured at the extremes of the specified analog signal range.

Note 5: Off isolation = 20log (VS/VD), VD = output, VS = input to off switch. Note 6: Between any two switches.

Note 7: Leakage parameters IS(OFF), ID(OFF), and ID(ON) are 100% tested at the maximum rated hot temperature and guaranteed by correlation at +25°C.
