Description
- Product Details
- The AD835 is a complete four-quadrant, voltage output analog multiplier, fabricated on an advanced dielectrically isolated complementary bipolar process. It generates the linear product of its X and Y voltage inputs with a −3 dB output bandwidth of 250 MHz (a small signal rise time of 1 ns). Full-scale (−1 V to +1 V) rise to fall times are 2.5 ns (with a standard RL of 150 Ω), and the settling time to 0.1% under the same conditions is typically 20 ns.
- Its differential multiplication inputs (X, Y) and its summing input (Z) are at high impedance. The low impedance output voltage (W) can provide up to ±2.5 V and drive loads as low as 25 Ω. Normal operation is from ±5 V supplies.
- Though providing state-of-the-art speed, the AD835 is simple to use and versatile. For example, as well as permitting the addition of a signal at the output, the Z input provides the means to operate the AD835 with voltage gains up to about ×10. In this capacity, the very low product noise of this multiplier (50 nV/√Hz) makes it much more useful than earlier products.
- The AD835 is available in an 8-lead PDIP package (N) and an 8-lead SOIC package (R) and is specified to operate over the −40°C to +85°C industrial temperature range.

- **Product Highlights**
- The AD835 is the first monolithic 250 MHz, four-quadrant voltage output multiplier.
- Minimal external components are required to apply the AD835 to a variety of signal processing applications.
- High input impedances (100 kΩ||2 pF) make signal source loading negligible.
- High output current capability allows low impedance loads to be driven.
- State-of-the-art noise levels achieved through careful device optimization and the use of a special low noise, band gap voltage reference.
- Designed to be easy to use and cost effective in applications that require the use of hybrid or board-level solutions.
- **Applications**
- Very fast multiplication, division, squaring
- Wideband modulation and demodulation
- Phase detection and measurement
- Sinusoidal frequency doubling
- Video gain control and keying
- Voltage-controlled amplifiers and filters
