Page 2: Introduction
Introduction www.ti.com Introduction To help the user investigate and evaluate the LM48580 performance and capabilities, a fully-populated demonstration board was created. Figure 1 shows the board. Connected to an external power supply (2.5 V ≤ V ≤ 5.5 V) and a signal source, the LM48580 demonstration board easily exercises features of the amplifier. -
Page 3: General Description
The LM48580 features one fully-differential input, a programmable gain pin, and a shutdown pin. The gain pin has three settings for 18 dB, 24 dB, and 30 dB. The LM48580 has a low power shutdown mode that reduces quiescent current consumption to 0.5 μA. -
Page 4: Connections
Minimize trace impedance of the power, ground and all output traces for optimum performance. Voltage loss due to trace resistance between the LM48580 and the load results in decreased output power and efficiency. Trace resistance between the power supply and ground has the same effect as a poorly regulated supply: increased ripple and reduced peak output power. - Page 5 Bill Of Materials www.ti.com Bill Of Materials Table 3 lists the bill of materials for the EVM.
