AD604ARS

AD604ARS is Analog Devices’ monolithic device in the AD604 family: a precision four-quadrant analog multiplier with a buffered output. It multiplies two analog input signals (or can be used as a divider, squarer, or phase-sensitive detector with proper biasing), making it useful for analog computation, modulators/demodulators, and signal-processing loops. The ARS suffix denotes a specific packaging/variant of the part (typically an 8-pin option) and lot information.
Key points:
- Four-quadrant analog multiplier with buffered output
- Can function as a multiplier, divider, squarer, or phase detector
- Suitable for modulators, demodulators, analog computers, RMS/ envelope detectors, and automatic gain control
- Designed for good dynamic range, linearity, and reasonably fast response within its operating range
- Requires appropriate power supply (single or dual) and biasing as per datasheet
For exact electrical specs (input ranges, bandwidth, offset, drift, supply voltage, temperature range) please consult the AD604 datasheet and the ARS packaging notes.

AD604ARS comes in an 8-pin small-outline package (SOIC-8).

- Pin count: 8 pins.
- Function: AD604ARS is a high-speed, precision instrumentation/differential amplifier used to amplify small differential signals (differential-input, typically single-ended output).

- Manufacturer: Analog Devices, Inc. (ADI)
- Company type: A global American semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits.

AD604ARS is typically used in a variety of analog-gain and signal-conditioning roles, including:
- Transimpedance and current-to-voltage conversion (e.g., photodiode amps)
- Instrumentation front-ends and general signal conditioning
- High-speed peak detectors and demodulators
- DC servo loop/error amplifier applications
- Small-signal RF/IF amplification and limiting
- Active filters and instrumentation amplifiers
