Exar unveil improved replacements for ADI op amps

Targeted at applications such as video surveillance and distribution systems, professional and IPC cameras, active filter circuits, coaxial cable drivers, and electronic white boards, the XR8051, XR8052 and XR8054 operational amplifiers can drive four video loads and operate from a wide supply voltage range. This accommodates general purpose, high-speed applications where dual supplies of up to ±6V or single supplies from +2.7V to +12V are required.

Gary Ross, Exar’s senior vice president and general manager, High Performance Analog product line, comments: “The XR805x family offers customers an opportunity to make their designs more power efficient and at the same time, improve performance. These pin for pin drop-in replacements allow customers to lower power consumption in existing platforms and offer performance enhancements that enable next generation designs.”

The XR805x family offers the best available combination of power consumption and performance:

• 175MHz -3dB Unity Gain Bandwidth,
• Rail-to-rail Output,
• Inputs extend 300mV beyond the Negative Supply Voltage,
• 50MHz Full Power Bandwidth (VO=2Vpp),
• 190V/µs Slew Rate,
• 0.03%/0.03 degree Differential Gain/Phase,
• 2.6mA per Channel,
• +/- 100mA Output Current,
• 92dB Open Loop Gain,
• 102dB Power Supply Rejection Ratio,
• 100dB Common Mode Rejection Ratio.

Availability

The XR805x family is available now and comes in the following packages:

• XR8051 – TSOT-5 / SOIC-8
• XR8052 – MSOP-8 / SOIC-8
• XR8054 – TSSOP-14 / SOIC-14

The suggested retail price for the XR805x family ranges from $0.69 for the single device to $1.34 for the quad device in 1,000-unit quantities
