LT1227CS8#PBF

Video Amps And Modules Overview

The LT1227CS8#PBF is a single-channel current feedback amplifier in an 8-lead SOIC package. It features a 140MHz bandwidth at AV=2, a 1100V/ms slew rate, and 30mA output drive current. Operating on supplies from –2V to –15V, it draws 10mA supply current. Key video specifications include 0.01% differential gain and 0.01° differential phase. The device includes a shutdown mode with input-to-output isolation of 70dB at 10MHz.

Video Amps And Modules Procurement Notes

Verify the specific suffix CS8 corresponds to the 8-lead plastic SOIC package and commercial temperature range (0°C to 70°C). Confirm RoHS compliance status via official documentation. Ensure logic levels for the shutdown pin interface are compatible with open collector or open drain configurations referenced in the datasheet.

Video Amps And Modules Selection Notes

Select this component when high bandwidth stability independent of gain is required. Consider the current feedback topology for applications demanding fast settling times and high slew rates. Evaluate the negative supply requirement (-2V to -15V) against system power constraints. Verify that the 30mA output current meets load drive requirements.

Video Amps And Modules Part Context

The LT1227 belongs to Analog Devices' family of high-speed video current feedback amplifiers. It utilizes a proprietary complementary bipolar process. Dual and quad versions of this architecture are available as the LT1229 and LT1230 respectively. The device is designed to upgrade performance in legacy video systems using standard pinouts.

Video Amps And Modules FAQ

How does the shutdown feature affect input-to-output isolation?

In shutdown mode, the device achieves 70dB of input-to-output isolation at 10MHz for input amplitudes up to 10V peak-to-peak.

What is the recommended method to interface logic to the shutdown pin?

The shutdown pin interfaces to open collector or open drain logic. Grounding the pin enables shutdown, while leaving it open allows normal operation.
