LT1469  
Dual 90MHz, 22V/µs  
16-Bit Accurate Operational Amplifier  
FEATURES  
DESCRIPTION  
The LT®1469 is a dual, precision high speed operational  
amplifierwith16-bitaccuracyand900nssettlingto150μV  
for 10V steps. This unique blend of precision and AC  
performance makes the LT1469 the optimum choice for  
highaccuracyapplicationssuchasDACcurrent-to-voltage  
conversion and ADC buffers. The initial accuracy and drift  
characteristicsoftheinputoffsetvoltageandinvertinginput  
bias current are tailored for inverting applications.

22V/μs Slew Rate  
Low Distortion: –96.5dB for 100kHz, 10V

Maximum Input Offset Voltage Drift: 3μV/°C  
Maximum Inverting Input Bias Current: 10nA  
Minimum DC Gain: 300V/mV  
Minimum Output Swing into 2k: 12.8V  
Unity-Gain Stable  
Input Noise Voltage: 5nV/√Hz  
Input Noise Current: 0.6pA/√Hz  
Total Input Noise Optimized for 1kΩ < R < 20kΩ  
Specified at 5V and 15V Supplies  
The 90MHz gain bandwidth ensures high open-loop gain  
at frequency for reducing distortion. In noninverting ap-  
plications such as an ADC buffer, the low distortion and  
DC accuracy allow full 16-bit AC and DC performance.  
S
The 22V/μs slew rate of the LT1469 improves large signal  
performance compared to other precision op amps in  
applications such as active filters and instrumentation  
amplifiers.  
APPLICATIONS  
n
Precision Instrumentation  
The LT1469 is available in a space saving 4mm × 4mm  
leadless package, as well as in small outline and DIP pack-  
ages. A single version, the LT1468, is also available.
