120MHz Current Feedback Amplifier
Features
The EL2030 is a very fast, wide
bandwidth amplifier optimized for
gains between -10 and +10. Built using
• -3dB bandwidth = 120MHz, A = 1
V
• -3dB bandwidth = 110MHz, A = 2
V
• 0.01% differential gain and 0.01° differential phase (NTSC,
PAL)
the Elantec monolithic Complementary Bipolar process, this
amplifier uses current mode feedback to achieve more
bandwidth at a given gain than a conventional voltage
feedback operational amplifier.
• 0.05% differential gain and 0.02° differential phase
(HDTV)
Due to its wide operating supply range (±15V) and extremely
high slew rate of 2000V/µs, the EL2030 drives ±10V into
200Ω at a frequency of 30MHz, while achieving 110MHz of
• Slew rate 2000V/µs
• 65mA output current
• Drives ±10V into 200Ω load
• Characterized at ±5V and ±15V
• Low voltage noise
small signal bandwidth at A = +2. This bandwidth is still
95MHz for a gain of +10. On ±5V supplies the amplifier
V
maintains a 90MHz bandwidth for A = +2. When used as a
V
unity gain buffer, the EL2030 has a 120MHz bandwidth with
the gain precision and low distortion of closed loop buffers.
• Current mode feedback
• Settling time of 40ns to 0.25% for a 10V step
• Output short circuit protected
• Low cost
The EL2030 features extremely low differential gain and
phase, a low noise topology that reduces noise by a factor of
2 over competing amplifiers, and settling time of 40ns to
0.25% for a 10V step. The output is short circuit protected. In
addition, datasheet limits are guaranteed for ±5V and ±15V
supplies.
