12MHz Rail-to-Rail Input-Output Operational Amplifier
EL5120T
The EL5120T is a high voltage rail-to-rail input-output amplifier
with low power consumption. The EL5120T is a single amplifier
that exhibits beyond the rail input capability, rail-to-rail output
capability, and is unity gain stable.
The operating voltage range is from 4.5V to 19V. It can be
configured for single or dual supply operation, and typically
consumes only 750µA. The EL5120T has an output short circuit
capability of ±200mA and a continuous output current capability
of ±70mA.
The EL5120T features a slew rate of 12V/µs. Also, the device
provides common mode input capability beyond the supply rails,
rail-to-rail output capability, and a bandwidth of 12MHz (-3dB).
This enables the amplifier to offer maximum dynamic range at
any supply voltage. These features make the EL5120T an ideal
amplifier solution for use in TFT-LCD panels as a V_COM or static
gamma buffer, and in high speed filtering and signal conditioning
applications. Other applications include battery power and
portable devices, especially where low power consumption is
important.
The EL5120T is available in small 5 Ld TSOT package. It features a
standard operational amplifier pinout. The device operates over
an ambient temperature range of -40°C to +85°C.
