The MAX4613 quad analog switch features on-resistance matching (4Ω max) between switches and guarantees on-resistance flatness over the signal range (9Ω max). This low on-resistance switch conducts equally well in either direction. It guarantees low charge injection (10pC max), low power consumption (35µW max), and an electrostatic discharge (ESD) tolerance of 2000V minimum per Method 3015.7. The new design offers lower off leakage current over temperature (less than 5nA at +85°C).The MAX4613 quad, single-pole/single-throw (SPST) analog switch has two normally closed switches and the two normally open switches. Switching times are less than 250ns for tON and less than 70ns for tOFF. Operation is from a single +4.5V to +40V supply or bipolar ±4.5V to ±20V supplies.ApplicationsAudio-Signal RoutingBattery-Powered ApplicationsCommunication SystemsGuidance and Control SystemsHeads-Up DisplaysMilitary RadiosModems/FaxesPBX, PABXSample-and-Hold CircuitsTest Equipment

The dual MAX492, quad MAX494, and single MAX495 operational amplifiers combine excellent DC accuracy with rail-to-rail operation at the input and output. Since the common-mode voltage extends from VCC to VEE, the devices can operate from either a single supply (+2.7V to +6V) or split supplies (±1.35V to ±3V). Each op amp requires less than 150µA supply current. Even with this low current, the op amps are capable of driving a 1kΩ load, and the input referred voltage noise is only 25nV/√Hz. In addition, these op amps can drive loads in excess of 1nF.The precision performance of the MAX492/MAX494/MAX495, combined with their wide input and output dynamic range, low-voltage single-supply operation, and very low supply current, makes them an ideal choice for battery-operated equipment and other low-voltage applications. The MAX492/MAX494/MAX495 are available in DIP and SO packages in the industry-standard op-amp pin configurations.

The MAX500 is a quad, 8-bit, voltage-output digital-to-analog converter (DAC) with a cascadable serial interface. The IC includes four output buffer amplifiers and input logic for an easy-to-use, two- or three-wire serial interface. In a system with several MAX500s, only one serial data line is required to load all the DACs by cascading them. The MAX500 contains double-buffered logic and a 10-bit shift register that allows all four DACs to be updated simultaneously using one control signal. There are three reference inputs so the range of two of the DACs can be independently set while the other two DACs track each other.The MAX500 achieves 8-bit performance over the full operating temperature range without external trimming.ApplicationsArbitrary Function GeneratorsAutomated Test Equipment (ATE)Digital Gain and Offset ControlIndustrial Process ControlsMinimum Component Count Analog Systems
