SLOS432APRIL 2004  
VERY LOW-POWER, HIGH-SPEED, RAIL-TO-RAIL INPUT AND OUTPUT  
VOLTAGE-FEEDBACK OPERATIONAL AMPLIFIER  
FEATURES  
DESCRIPTION  
Very Low Quiescent Current: 750 µA (at 5 V)  
Fabricated using the BiCom-II process, the THS4281  
is a low-power, rail-to-rail input and output volt-  
age-feedback operational amplifier designed to  
operate over a wide power supply range of 2.7-V to  
15-V single supply, and ±1.35-V to ±7.5-V dual  
supply. Consuming only 750 µA with a unity gain  
bandwidth of 90 MHz and a high 35-V/µs slew rate,  
the THS4281 allows portable or other power-sensitive  
applications to realize high performance with minimal  
power. To ensure long battery life in portable appli-  
cations, the quiescent current is trimmed to be less  
than 900 µA at 25°C, and 1 mA from –40°C to 85°C.  
Rail-to-Rail Input and Output:  
– Common-Mode Input Voltage Extends  
400 mV Beyond the Rails  
– Output Swings Within 150 mV From the  
Rails  
Wide -3 dB Bandwidth at 5 V:  
– 90-MHz @ Gain = +1, 40 MHz @ Gain = +2  
High Slew Rate: 35 V/µs  
Fast Settling Time (2-V Step):  
– 78 ns to 0.1%  
The THS4281 is a true single-supply amplifier with a  
specified common-mode input range of 400 mV  
beyond the rails. This allows for high-side current  
sensing applications without phase reversal con-  
cerns. Its output swings to within 40 mV from the rails  
with 10-kloads, and 150 mV from the rails with  
1-kloads.  
– 150 ns to 0.01%  
Low Distortion @ Gain = +2, VO = 2-Vpp, 5 V:  
– -91 dBc at 100 kHz, -67 dBc at 1 MHz  
Input Offset Voltage: 2.5 mV (Max at 25°C)  
Output Current >30 mA (10-Load, 5 V)  
Low Voltage Noise of 12.5 nV/Hz  
Supply Voltages: +2.7 V, 3 V, +5 V, ±5 V, +15 V  
Packages: SOT-23, MSOP, and SOIC  
The THS4281 has a good 0.1% settling time of 78 ns,  
and 0.01% settling time of 150 ns. The low THD of  
-87 dBc at 100 kHz, coupled with a maximum offset  
voltage of less than 2.5 mV, makes the THS4281 a  
good match for high-resolution ADCs sampling less  
than 2 MSPS.  
APPLICATIONS  
Portable/Battery-Powered Applications  
High Channel Count Systems  
ADC Buffer  
Active Filters  
Current Sensing  
The THS4281 is offered in a space-saving SOT-23-5  
package, a small MSOP-8 package, and the industry  
standard SOIC-8 package.
