Tiny amplifiers deliver high performance for challenging system designs

From Texas Instruments come a tiny operational amplifier (op amp) and low-power comparators at 0.64 mm2.

As the first amplifiers in the compact X2SON package, the TLV9061 op amp and TLV7011 family of comparators enable engineers to reduce their system size and cost, while maintaining high performance in a variety of Internet of Things (IoT), personal electronics and industrial applications, including mobile phones, wearables, optical modules, motor drives, smart grid and battery-powered systems.

With a high gain bandwidth of 10MHz, fast slew rate at 6.5V per micro seconds and low-noise spectral density of 10 nano volts per √Hz, the TLV9061 op amp is designed for use in wide-bandwidth, high-performance systems.

The TLV7011 family of nano power comparators delivers a faster response time with propagation delays down to 260 nano seconds.

Additionally, both devices support rail-to-rail inputs with low-voltage operation down to 1.8V, enabling ease-of-use in battery-powered applications.

In addition to its tiny size, the TLV9061 op amp also features integrated EMI filtering inputs. This helps provide resilient performance for systems prone to RF noise, while reducing the need for external discrete circuitry.

Two times lower offset drift and typical input bias across a full temperature range, -40 to 125 degrees C, creates a more precise signal chain solution compared with other small devices, states the company.

Meanwhile the comparators’ no phase reversal and integrated internal hysteresis for overdriven inputs increase design flexibility and reduce the need for external components.

With power down to 335 nano amps and fast propagation delay down to 260 nano seconds, the TLV7011 nanopower comparators enable low-power systems to monitor signals and respond quickly.

Designers can download the TINA-TI SPICE model to simulate their designs and predict circuit behaviour when using the TLV9061 op amp and TLV7011 family of comparators.

Engineers can jump-start their small brushed DC servo drive designs using the TLV9061 op amp with the 10.8V/15W, >90 per cent efficiency, 2.4cm2, power stage reference design.

Also, they can quickly and easily evaluate the TLV7011 comparators with the DIP adapter evaluation module.
