LM6181 100 mA, 100 MHz Current Feedback Amplifier 1 Features(1) 3 Description
The LM6181 current-feedback amplifier offers an • Slew Rate: 2000 V/μs 1 unparalleled combination of bandwidth, slew-rate, • Settling Time (0.1%): 50 ns and output current. The amplifier can directly drive up • Characterized for Supply Ranges: to 100 pF capacitive loads without oscillating and a ± 5 V and ±15 V 10-V signal into a 50-Ω or 75-Ω back-terminated coax cable system over the full industrial temperature • Low Differential Gain and Phase Error: range. This represents a radical enhancement in 0.05%, 0.04° output drive capability for an 8-pin PDIP high-speed • High Output Drive: ±10 V into 100 Ω amplifier making it ideal for video applications. • Ensured Bandwidth and Slew Rate Built on TI's advanced high-speed VIP™ II (Vertically • Improved Performance Over EL2020, OP160, Integrated PNP) process, the LM6181 employs AD844, LT1223 and HA5004 current-feedback providing bandwidth that does not vary dramatically with gain; 100 MHz at AV = −1, (1) Typical, unless otherwise noted 60 MHz at AV = −10. With a slew rate of 2000V/μs, 2nd harmonic distortion of −50 dBc at 10 MHz and settling time of 50 ns (0.1%) the LM6181 dynamic
