Overview

Voltage feedback
Wide output swing
- 18.4 V p-p differential, R_{LOAD, DIFF} = 20 Ω from 12 V supply
High output current
- Linear output current of 450 mA peak
Low distortion
- −65 dBc for Profile 8b at 20.4 dBm
- −55 dBc for Profile 17a at 14.5 dBm
High speed
- 85 MHz bandwidth (A_{V DIFF} = 5)

The AD8398A comprises two high speed, voltage feedback operational amplifiers. When configured as a differential line driver, the AD8398A is an ideal choice for ADSL2+, VDSL2, and power line communications (PLC) applications. It has high output current, high bandwidth, and fast slew rate, combined with exceptional multitone power ratio (MTPR) and commonmode stability. The AD8398A is available in a thermally enhanced 4 mm × 4 mm, 16-lead LFCSP.

The AD8398A incorporates power management functionality via two CMOS-compatible control pins, PD0 and PD1. These pins select one of four operating modes: full power, medium power, low power, or complete power-down. In the power-down mode, the quiescent current drops to 0.7 mA.

The AD8398A operates in the industrial temperature range of −40°C to +85°C.
