XD7650-14 – Operational Amplifier – Xinluda

The Xinluda XD7650-14 is a super chopper-stabilized precision operational amplifier in a 14-pin DIP package, offering ultra-low input offset voltage and very low input bias current for instrumentation and precision signal-conditioning applications.

The XD7650-14 from Xinluda is a super chopper-stabilized precision operational amplifier supplied in a 14-pin dual-in-line (DIP-14) package. The 14-lead version of the XD7650 family adds provision for an external clock connection, making it well suited to precision DC and low-frequency applications where extremely low input offset voltage and offset drift are critical. The chopper-stabilization is user-transparent, virtually eliminating the intermodulation effects, chopping spikes, and overrange lockup associated with traditional chopper amplifiers. It is widely regarded as a functional alternative to the industry-standard 7650-series chopper-stabilized amplifiers.

Key Features

• Super chopper-stabilized topology for exceptionally low input offset voltage (typ. 5 uV)
• Guaranteed maximum input bias current of 10 pA
• Extremely high open-loop gain: 150 dB
• Extremely high CMRR and PSRR: 140 dB
• Wide common-mode voltage range: +3.5 V to -5 V
• Slew rate: 2.5 V/us
• Wide bandwidth: 2 MHz
• Supply voltage range: 4.5 V to 16 V
• Reduced supply current: 2 mA (typ.)
• Operating temperature range: 0 C to +70 C
• 14-pin DIP package with external-clock provision; internally compensated for unity-gain operation

Applications

• Precision instrumentation amplifiers
