Standard Linear ICs Week

Let’s leave aside the evil Huricane Sandy, which has left eastcoasters powerless and angry (oops: maybe I am just talking about me), but this week is a special week for Electronic Products . Not only we have election day this week, but we also have Standard Linear ICs week.

Here are some standard linear ICs in case you missed them.

Touchstone Semiconductor offers the TS12011 and TS12012, 0.9-µW operational amplifier, comparator, and voltage reference in one IC.

This 10-times reduction in power consumption and operation down to 0.8 V enables always-on, single-cell operation that was not previously possible. They are fully specified over the –40° to +85°C temperature range. Each is available in a low-profile 10-pin 2 x 2-mm TDFN package.

Both the analog comparator and the op-amp feature rail-to-rail input stages. The analog comparator has ±7.5 mV of internal hysteresis for clean, chatter-free output switching. The internal reference is designed to sink or source up to 0.1-µA load currents.

Microchip recently announced the MCP6H7X/8X/9X low-power,general-purpose operational amplifiers, which expand the range to 12-V supply voltages. Because they maintain the same pin outs and features of the company’s existing 6- and 16-V families, designers can easily migrate to the ideal voltage rail, along with the new families’ higher-speed gain bandwidth product (GBWP) range of 2.7 to 10 MHz. Additionally, all nine members of the new families are available in single, dual, and quad configurations.

The MCP6H71, MCP6H72, MCP6H81, MCP6H82, MCP6H91, and MCP6H92 are all available in 8-pin SOIC and 2 x 3-mm TDFN packages. The MCP6H74, MCP6H84, and MCP6H94 are all available in 14-pin SOIC and TSSOP packages.Linear Technology also recently introduced three low-power 16-bit 20-Msample/s A/D converters: the LTC2269, LTC2270, and LTC2271. The parts offer the lowest input-referred noise and tight integral nonlinearity error (INL) for very high precision dc measurements. With only 46-μVrms input noise and maximum guaranteed INL error of ±2.3 LSB, these ADCs are suitable for very low noise, high linearity sampling applications such as digital x-ray, infrared and medical imaging, pachymeters, spectrometry, and cytometry. These devices achieve SNR performance of 84 dB and SFDR of 99 dB at baseband.The ADCs themselves consume approximately 80 mW/channel. Further power savings can be achieved by placing the devices in standby (12 mW) or shutdown (0.5 mW), making them ideal for handheld test and measurement applications.cnickolas@hearst.com
