LT1468

90MHz, 22V/µs

16-Bit Accurate

Operational Ampliﬁer

DESCRIPTION

FEATURES

TheLT^®1468isaprecisionhighspeedoperationalampliﬁer

with 16-bit accuracy and 900ns settling to 150μV for 10V

signals.ThisuniqueblendofprecisionandACperformance

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 character-

istics 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 (A = –1, 150μV, 10V Step)

Low Distortion, –96.5dB for 100kHz, 10V

P-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

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.

Unity Gain Stable

Input Noise Voltage: 5nV/√Hz

Input Noise Current: 0.6pA/√Hz

Total Input Noise Optimized for 1k < R < 20k

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.

Speciﬁed at 5V and 15V

APPLICATIONS
