iC-BM Quad Four-Quadrant Analog Multiplier

Product catalog summary

Features:
The iC-BM is a four-channel, four-quadrant analog multiplier designed as a replacement for the MLT04. It features four independent channels with a voltage output defined by W = 0.4 × X × Y, an analog input range of ±2.5 V, a bandwidth of 3.5 MHz, and low power dissipation. It is suitable for applications such as analog computation, squaring circuits, modulation and demodulation, and voltage-controlled amplifiers and filters. The device is available in an RoHS-compliant SO18W package.

Description:
The iC-BM consists of four analog multipliers, each utilizing a Gilbert cell multiplier with a 0.4 scale factor, a linearization circuit, and a unity gain output amplifier. Internal bias currents are derived from an internal band-gap reference for higher precision, and all pins are ESD protected.

Pin Configuration:
The SO18W package includes pins for four channels, each with inputs X and Y, an output W, and a ground pin. The device operates with a positive power supply (VCC) of +5 V and a negative power supply (VEE) of -5 V.

Package Dimensions:
The dimensions for the SO18W package are provided in millimeters, with a recommended PCB footprint.

Absolute Maximum Ratings:
The device can withstand a maximum VCC of 7 V and a minimum VEE of -7 V. The voltage at pins X, Y, and W should remain within -7 V to 7 V. The chip and storage temperatures range from -40°C to 150°C.

Thermal Data:
Operating conditions include a VCC of 5 V ±0.25 V, VEE of -5 V ±0.25 V, and a thermal resistance of 68 K/W. The operating ambient temperature range is -40°C to 85°C.

Electrical Characteristics:
The device operates with a positive supply voltage range of 4.75 V to 5.25 V and a negative supply voltage range of -5.25 V to -4.75 V. The power dissipation is between 150 mW and 200 mW. Multiplier performance includes offset voltages, scale factor, total error, and linearity error specifications. Dynamic performance includes a bandwidth of 3.5 MHz, a slew rate of 30 V/µs, and a settling time of 1 µs.

Ordering Information:
The iC-BM is available in the SO18W package. For technical support and ordering, contact iC-Haus GmbH in Germany or visit their website for local distributors.
