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.

90MHz Gain Bandwidth, f = 100kHz

Maximum Input Offset Voltage: 125μV

Settling Time: 900ns (A = –1, 150μV, 10V Step)

22V/μs Slew Rate

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

P-P

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.

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

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.
