ADL5519ACPZ-R7 (ANALOG DEVICES)

The ADL5519ACPZ-R7 is a 62dB Dual Log Detector/Controller operating from 1MHz to 10GHz. The ADL5519 is a dual-demodulating logarithmic amplifier that incorporates two AD8317s. It can accurately convert an RF input signal into a corresponding decibel-scaled output. The ADL5519 provides accurately scaled, independent, logarithmic output voltages for both RF measurement channels. The device has two additional output ports, OUTP and OUTN, that provide the measured differences between the OUTA and OUTB channels. The on-chip channel matching makes the log amp outputs insensitive to temperature and process variations. The temperature sensor pin provides a scaled voltage that is proportional to the temperature over the operating temperature range of the device. The ADL5519 maintains accurate log conformance for signals from 1MHz to 8GHz and provides useful operation to 10GHz. The ±3dB dynamic range is typically 62dB and has a ±1dB dynamic range of >50dB (re: 50R).
