DESCRIPTIO  
FEATURES  
The LT®1468 is a precision high speed operational ampli-  
fier with 16-bit accuracy and 900ns settling to 150µV for  
10V signals. This unique blend of precision and AC perfor-  
mance makes the LT1468 the optimum choice for high  
accuracy applications such as DAC current-to-voltage  
conversion and ADC buffers. The initial accuracy and drift  
characteristics of the input offset voltage and inverting  
input bias current are tailored for inverting applications.  
90MHz Gain Bandwidth, f = 100kHz  
22V/µs Slew Rate  
Settling Time: 900ns (AV = –1, 150µV, 10V Step)  
Low Distortion, 96.5dB for 100kHz, 10VP-P  
Maximum Input Offset Voltage: 75µV  
Maximum Input Offset Voltage Drift: 2µV/°C  
Maximum (–) Input Bias Current: 10nA  
Minimum DC Gain: 1000V/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 1k < RS < 20k  
Specified at ±5V and ±15V  
The 90MHz gain bandwidth ensures high open-loop gain  
atfrequencyforreducingdistortion. Innoninvertingappli-  
cations such as an ADC buffer, the low distortion and DC  
accuracy allow full 16-bit AC and DC performance.  
The 22V/µs slew rate of the LT1468 improves large-signal  
performance in applications such as active filters and  
instrumentation amplifiers compared to other precision  
op amps.
