What this instrumentation amp brings to a precision front-end
The LT1102ACN8#PBF is a single-channel instrumentation amplifier in an 8-pin DIP package. It delivers a 30V/µs slew rate and 3.5 MHz gain-bandwidth product.
Supply voltage range — 18 V to 36 V
The LT1102ACN8#PBF requires a minimum 18 V supply and can handle up to 36 V across the rails. Quiescent supply current is 3.3 mA.
Slew rate and bandwidth — signal fidelity at speed
The 30V/µs slew rate is notably higher than typical precision instrumentation amps. Combined with 3.5 MHz GBP, this part can handle fast transients from bridge sensors or multiplexed inputs without significant slew-induced distortion. The 3 pA input bias current preserves accuracy when driving high-impedance sources like photodiodes or pH probes.
Lifecycle and sourcing
The LT1102ACN8#PBF carries an active lifecycle status with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect. For dual-sourcing, the AD625KNZ is a through-hole instrumentation amp in the same 8-DIP footprint, though its 25 MHz GBP and 5 V/µs slew rate shift the dynamic response — verify timing and settling in your application before substituting.
