Stable in Gain AV ≥ 2 (AV = –1)
The LT®1468-2 is a precision high speed operational ampli- n
200MHz Gain Bandwidth Product
fier with 16-bit accuracy, decompensated to be stable in a n
30V/μs Slew Rate
gain of 2 or greater. The combination of precision and AC n
Settling Time: 800ns (10V Step, 150µV)
performance makes the LT1468-2 the optimum choice for n
Specified at ±5V and ±15V Supplies
high accuracy applications such as DAC current-to-voltage n Low Distortion, – 96.5dB for 100kHz, 10VP-P conversion and ADC buffers. The initial accuracy and drift n Maximum Input Offset Voltage: 75µV characteristics of the input offset voltage and inverting n Maximum Input Offset Voltage Drift: 2µV/°C input bias current are tailored for inverting applications. n Maximum (–) Input Bias Current: 10nA The 200MHz gain bandwidth ensures high open-loop gain n Minimum DC Gain: 1000V/mV at frequency for reducing distortion. In noninverting ap- n Minimum Output Swing into 2k: ±12.8V plications such as an ADC buffer, the low distortion and n Input Noise Voltage: 5nV/√Hz DC accuracy allow full 16-bit AC and DC performance. n Input Noise Current: 0.6pA/√Hz The high slew rate of the LT1468-2 improves large-signal n Total Input Noise Optimized for 1k < RS < 20k performance in applications such as active filters and n Available in an 8-Lead Plastic SO Package instrumentation amplifiers compared to other precision and 8-Lead DFN Package op amps.
