LT1468

90MHz, 22V/µs

16-Bit Accurate

Operational Amplifier

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 (A_V= –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

Unity Gain Stable

Input Noise Voltage: 5nV/√Hz

Input Noise Current: 0.6pA/√Hz

Total Input Noise Optimized for 1k < R_S< 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.
