The ADE7761B is a high accuracy, fault-tolerant, electrical energy measurement IC intended for use with 2-wire distribution systems. The part specifications surpass the accuracy requirements as quoted in the IEC 62053-21 standard. The only analog circuitry used on the ADE7761B is in the ADCs and reference circuit. All other signal processing (such as multiplication and filtering) is carried out in the digital domain. This approach provides superior stability and accuracy over extremes in environmental conditions and over time. The ADE7761B incorporates a fault detection scheme similar to the ADE7751 by continuously monitoring both phase and neutral currents. A fault is indicated when the currents differ by more than 6.25%.The ADE7761B incorporates a missing neutral detection scheme by continuously monitoring the input voltage. When a missing neutral condition is detected (no voltage input), the ADE7761B continues billing based on the active current signal (see the Missing Neutral Mode section). The missing neutral condition is indicated when the FAULT pin goes high. The ADE7761B supplies average active power information on the low frequency outputs, F1 and F2. The CF logic output gives instantaneous active power information.The ADE7761B includes a power supply monitoring circuit on the VDD supply pin. Internal phase matching circuitry ensures that the voltage and current channels are matched. An internal no-load threshold ensures that the ADE7761B does not exhibit any creep when there is no load.

The ADG526A and ADG527A are CMOS monolithic analog multiplexers with 16 single channels and dual 8 channels, respectively. On-chip latches facilitate microprocessor interfacing. The ADG526A switches one of 16 inputs to a common output, depending on the state of four binary addresses and an enable input. The ADG527A switches one of eight differential inputs to a common differential output, depending on the state of three binary addresses and an enable input. Both devices have TTL and 5 V CMOS logic-compatible digital inputs. The ADG526A and ADG527A are designed on an enhanced LC2MOS process that gives an increased signal capability of VSS to VDD and enables operation over a wide range of supply voltages. The devices can comfortably operate anywhere in the 10.8 V to 16.5 V single- or dual-supply range. These multiplexers also feature high switching speeds and low RON. PRODUCT HIGHLIGHTS Single- or Dual-Supply Specifications with a Wide Tolerance. The devices are specified in the 10.8 V to 16.5 V range for both single and dual supplies. Easily Interfaced. The ADG526A and ADG527A can be easily interfaced with microprocessors. The WR signal latches the state of the address control lines and the enable line. The RS signal clears both the address and enable data in the latches, resulting in no output (all switches off). RS can be tied to the microprocessor reset pin. Extended Signal Range. The enhanced LC2MOS processing results in a high breakdown and an increased analog signal range from VSS to VDD. Break-Before-Make Switching. Switches are guaranteed break-before-make so that input signals are protected against momentary shorting. Low Leakage. Leakage currents in the range of 20 pA make these multiplexers suitable for high precision circuits.APPLICATIONS Data acquisition systems Communication systems Automatic test equipment Microprocessor controlled systems

The ADG601 / ADG602 are monolithic, CMOS single-pole single-throw (SPST) switches with on resistance typically less than 2.5 Ω. The low on-resistance flatness makes the ADG601 / ADG602 ideally suited to many applications, particularly those requiring low distortion. These switches are ideal replacements for mechanical relays because they are more reliable, have lower power requirements, and are available in much smaller package sizes.The ADG601 is a normally open (NO) switch, and the ADG602 is a normally closed (NC) switch. Each switch conducts equally well in both directions when the device is on, with the input signal range extending to the supply rails.The switches are available in tiny, 6-lead SOT-23; 8-lead MSOP; and 820 μm × 2255 μm die.PRODUCT HIGHLIGHTS Low on resistance (2 Ω typical) Dual ±2.7 V to ±5.5 V or single +2.7 V to +5.5 V supplies Tiny, 6-lead SOT-23; 8-lead MSOP; and 820 μm × 2255 μm die Rail-to-rail input signal rangeAPPLICATIONS Automatic test equipment Power routing Communication systems Data acquisition systems Sample-and-hold systems Avionics Relay replacement Battery-powered systems

The ADG609 is a monolithic CMOS analog multiplexer comprising four differential channels. The ADG609 switches one of four differential inputs to a common differential output as determined by the 2-bit binary address lines A0 and A1. An EN input on both devices is used to enable or disable the device. When disabled, all channels are switched OFF.The ADG609 is designed on an enhanced LC2 MOS process which provides low power dissipation yet gives high switching speed and low on resistance. Each channel conducts equally well in both directions when ON and has an input signal range which extends to the supplies. In the OFF condition, signal levels up to the supplies are blocked. All channels exhibit break before make switching action preventing momentary shorting when switching channels. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.
