3 Description
The LMP8350 device is an ultra low distortion fully-
differential amplifier designed for driving high- performance precision analog-to-digital converters
ADC). As part of the PowerWise™ family, a unique
mode enable pin allows the user to choose from three
different operating modes, trading power consumption for dynamic performance.
The high power mode is optimized for highest AC performance. The low noise, wide bandwidth, and
fast slew rate make the LMP8350 ideal for driving 24-
bit ADCs with input sampling rates of 10 MHz or less.
The medium power mode is optimized for precision
DC performance, and can be used to drive 24-bit
ADCs with input sampling rates of 6 MHz or less. The
low power mode is a trade-off between AC
performance and quiescent current for power•
sensitive applications. The disable mode fully shuts down the amplifier for further standby power savings.
The fully differential architecture of this device allows for easy implementation of a single-ended to fullydifferential
output conversion. Driving a 3-Vpp, 1-kHz
output sine wave with the amplifier powered by ±3.3-
V rails in high power mode yields 0.000098%
THD+N.
The LMP8350 is part of the LMP™ precision amplifier
family, and is offered in the 8-pin SOIC package, with
an operating temperature range of −40°C to +85°C.
