Product Details
General Description
The DS1870 is a dual-channel bias controller targeted toward class AB LDMOS RF power-amplifier applications. It uses lookup tables (LUTs) to control 256-position potentiometers based on the amplifier’s temperature and drain voltage or current (or other external monitored signal). With its internal temperature sensor and multichannel A/D converter (ADC), the DS1870 provides a cost-effective solution that improves the amplifier’s efficiency by using nonlinear compensation schemes that are not possible with conventional biasing solutions.Features
♦ Two-Channel Solution for Programmable RF Bias Control♦ The Potentiometer’s Position is Automatically Updated to Compensate for the Ambient Temperature and the Drain Voltage or Current
♦ A Five-Channel, 13-Bit ADC Continuously Monitors the Ambient Temperature, VCC, VD, ID1, and ID2
♦ Hi/Lo Alarms for Each ADC Channel can Trigger a Fault Output
♦ Nonvolatile Memory for the Device Settings, Lookup Tables, and 32-Bytes of User Memory
♦ I2C™-Compatible Serial Interface with Up to Eight Devices on the Same Serial Bus
♦ Single 5V Power Supply
♦ Small 16-Pin TSSOP Package
♦ -40°C to +95°C Operational Temperature Range
