Description

AD843AQ is an Analog Devices high-speed operational amplifier. It’s designed for fast signal conditioning in instrumentation, video, and data-acquisition front ends. It combines wide bandwidth, fast slew rate, and low distortion to accurately amplify fast-edge signals. The -AQ suffix indicates a specific package/grade variant; refer to the datasheet for exact electrical specs, pinout, and operating temperature. Typical uses include transimpedance amplifiers for photodiodes, high-speed instrumentation front ends, video amplifiers, and active filters. For precise performance, consult the AD843AQ datasheet and the package/temperature specifications.

Equivalent

Equivalent parts depend on your specs. AD843AQ is a high‑speed BiMOS op‑amp. Close cross references include Analog Devices ADA4899‑1/ADA4892‑1 and TI OPA846/OPA827. Exact drop‑in equivalents vary by GBW, slew rate, supply rails, and package. For a precise cross, use ADI’s Cross Reference tool or share your target specs (GBW, SR, V+, V−, package).

Features

AD843AQ features (op-amp):
- High-speed, precision op-amp for fast signal processing
- Wide bandwidth with high slew rate
- Low input offset voltage and low input bias current
- Low noise for clean amplification
- Rail-to-rail input and rail-to-rail output on a single supply
- Wide supply voltage range and broad operating temperature range
- Good power-supply rejection (PSRR) and common-mode rejection (CMRR)
- Suitable for precision front-ends, active filters, and ADC interfaces
- RoHS-compliant packaging options (standard lead-free packages)
Note: For exact electrical specs (GBW, SR, offset, noise, supply range, temp range), consult the AD843AQ datasheet.

Pinout

AD843AQ is an 8-pin device that contains two operational amplifiers (a dual op-amp). Typical pinout (dual op-amp): Pin 1 = Output A, Pin 2 = In− A, Pin 3 = In+ A, Pin 4 = V−, Pin 5 = In+ B, Pin 6 = In− B, Pin 7 = Output B, Pin 8 = V+. For exact package pin mapping, check the specific datasheet (DIP-8/SOIC-8 variants).

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits for industrial, automotive, communications, and consumer markets.

Application

AD843AQ is a high-speed, precision amplifier (automotive-grade). Common application areas include:
- Automotive sensor front-ends and ECU signal conditioning
- Medical instrumentation and biosignal amplification
- Industrial/process control and data acquisition front ends
