MAXIM Manuals

The MAX4649 is a low on-resistance, single-pole double-throw (SPDT) analog switch from Texas Instruments. Its on-resistance is a maximum of 45 ohms and flat (7 ohms maximum) over the specified signal range. The MAX4649 can handle Rail-to-Rail® analog signals and conducts analog or digital signals equally well in either direction. This switch operates from a single +9V to +36V supply, or from ±4.5V to ±20V dual supplies. The primary application areas are in the switching and routing of signals in telecommunications and test equipment. The MAX4649 features a switch transition time of 130ns maximum at +25°C, and a guaranteed break-before-make switching time of 5ns. Off-leakage current is only 2nA maximum at +25°C. The MAX4649 is available in a tiny 8-pin SOT23 package.

The MAX4711/MAX4712/MAX4713 are fault-protected, Rail-to-Rail®, low-voltage analog switches featuring low on-resistance and guaranteed on-resistance flatness over the specified signal range.

The MAX8814 is an intelligent, stand-alone constant-current, constant-voltage (CCCV) thermally regulated linear charger designed for charging a single-cell lithium-ion (Li+) battery. The IC integrates the current- sense circuit, MOSFET pass element, thermal- regulation circuitry, and eliminates the reverse-blocking Schottky diode to create the simplest and smallest charging solution for handheld equipment.

Maxim’s MAX4655–MAX4658 are medium-voltage CMOS analog switches with low on-resistance of 10Ω max, specifically designed to handle large switch cur- rents. With a switch capability of up to 400mA peak cur- rent and 300mA continuous current (MAX4655/ MAX4656), and up to 300mA peak current and 150mA continuous current (MAX4657/MAX4658), these parts can switch loads as low as 25Ω. They can replace reed relays with a million times the speed and virtually unlim- ited number of lifetime cycles. Normal power consump- tion is only 3mW, whether the switch is on or off. These parts are TTL/CMOS compatible and will switch any voltage within its power-supply range. These are SPST (single-pole/single-throw) switches. The MAX4655/MAX4657 are normally closed (NC), while the MAX4656/MAX4658 are normally open (NO). The difference between the MAX4655/MAX4656 and the MAX4657/MAX4658 is in the power dissipation of their packages. Refer to the Absolute Maximum Ratings and the Electrical Characteristics. The MAX4655–MAX4658 power-supply range is from ±4.5V to ±20V for dual-supply operation and +9V to +40V for single-supply operation. These switches can operate from any combination of supplies, within a 40V V+ to V- range. They conduct equally well in either direc- tion and can handle rail-to-rail analog signals. The off- leakage current is only 1nA max at TA = +25°C. They are available in 8-pin µMAX®, TDFN, and SO packages, with exposed paddle options for high-power application

The MAX4533 is a quad, single-pole/double-throw (SPDT), fault-protected analog switch that is pin-compatible with the industry-standard MAX333 and MAX333A. It features fault-protected inputs and Rail-to-Rail® signal handling. The normally open (NO_ ) and normally closed (NC_ ) terminals are protected from overvoltage faults up to ±25V with power on and up to ±40V with power off. During a fault condition, NO_ and NC_ become high impedance with only nanoamperes of leakage current flowing to the source. In addition, the output (COM_) clamps to the appropriate polarity supply rail and provides up to ±10mA of load current. This ensures unambiguous rail-to-rail outputs when a fault occurs. The MAX4533 operates from dual ±4.5V to ±18V power supplies or a single +9V to +36V supply. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring both TTL and CMOS logic compatibility when using ±15V supplies or a +12V supply. On-resistance is 175Ω max and is matched between switches to 10Ω max. The off- leakage current is only 0.5nA at TA = +25°C and 10nA at TA = +85°C. Applications include redundant/backup systems, portable instruments, test equipment, data-acquisition, communications systems, industrial and process control, and avionics systems.

The MAX4051/4052/4053 series are low-voltage CMOS analog integrated circuits configured as an 8-channel multiplexer (MAX4051), two 4-channel multiplexers (MAX4052) and three single-pole/double-throw (SPDT) switches (MAX4053). A-suffix parts are fully characterized for on-resistance match, on-resistance flatness, and low leakage. These CMOS devices can operate continuously with dual power supplies ranging from ±2.7 V to ±8 V or a single supply between +2.7 V and +16 V. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 0.1 nA at +25°C or 5 nA at +85°C (MAX4051A/4052A/4053A). All digital inputs have 0.8 V to 2.4 V logic thresholds, ensuring TTL/CMOS-logic compatibility when using ±5 V or a single +5 V supply.

The MAX4659/MAX4660 are medium voltage CMOS analog switches with a low on-resistance and high switch current capability.

These new switches fea- ture fault-protected inputs and Rail-to-Rail signal- handling capability. All terminals are protected from overvoltage faults up to ±36V with power on and up to ±40V with power off. During a fault condition, the COM, NO, or NC terminal becomes an open circuit and only microamperes of leakage current flow from the source.

The MAX4708/MAX4709 are similar to the MAX4508/MAX4509, but these devices do not have clamp diodes to the supply rails on the switch outputs. These multiplexers feature fault-protected inputs, rail-to-rail signal-handling capability, and do not require power-supply sequencing. Both devices offer ±40V overvoltage protection with the supplies off, ±36V protection with the supplies on, and feature 400Ω (max) on-resistance with 15Ω (max) matching between channels.
