Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- The control is a 5-bit serial/parallel interface, and the attenuators operate with either single positive or dual (positive and negative) supply voltage.
- DAT-31A+ series models are produced by a unique CMOS process on silicon, offering the performance of GaAs with the advantages of conventional CMOS devices.
- Feature Advantages Wideband operation, specified from DC to 4.0 GHz Can be used in multiple applications such as communications, satellite and defense, reducing part count.
- Single positive supply models: (Model suffixes: -SP+ and –PP+) +2.3 to +3.6V+ Use of single positive supply simplifies power supply design.
- Dual supply models: (Model suffixes: -SN+ and –PN+) +2.7 to +3.6V (Positive) and -3.6 to -3.2V (Negative) Dual supply provides spurious-free operation.
- It also allows fast switching up to 1 MHz (vs.
- Useable over a wide range of supply voltages, +2.3/2.7 to 5.2V Wide range fo positive operating voltages allows the DAT-31A+ Series of models to be used in a wide range of applications.
Engineering review checklist
- Verify supply range, input common-mode range and output swing at the required load.
- Check offset, bias current, noise, bandwidth, slew rate and stability for the intended feedback network.
- Review supply decoupling, source impedance, capacitive-load behavior and thermal limits in the final layout.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
