Unity Gain Stability
The THS4211 and THS4215 are high slew rate, unity
gain stable voltage feedback amplifiers designed to
run from supply voltages as low as 5 V and as high
as 15 V. The THS4215 offers the same performance
as the THS4211 with the addition of power-down
capability. The combination of high slew rate, wide
bandwidth, low distortion, and unity gain stability
make the THS4211 and THS4215 high performance
devices across multiple ac specifications.
Wide Bandwidth: 1 GHz
High Slew Rate: 970 V/µs
Low Distortion
– –90 dBc THD at 30 MHz
– 130 MHz Bandwidth (0.1 dB, G = 2)
– 0.007% Differential Gain
– 0.003° Differential Phase
High Output Drive, IO = 200 mA
Excellent Video Performance
– 130 MHz Bandwidth (0.1 dB, G = 2)
– 0.007% Differential Gain
– 0.003° Differential Phase
Supply Voltages
Designers using the THS4211 are rewarded with
higher dynamic range over a wider frequency band
without the stability concerns of decompensated
amplifiers. The devices are available in SOIC, MSOP
with PowerPAD™, and leadless MSOP with
PowerPAD packages.
