Op amps, comparators said to be smallest ever




Texas Instruments introduced the industry’s smallest operational amplifier 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.Op amps, comparators said to be smallest ever

With a high gain bandwidth (GBW) of 10 MHz, fast slew rate at 6.5 V/µs and low-noise spectral density of 10 nV/√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 ns, while consuming 50 percent less power than competitive comparators. Additionally, both devices support rail-to-rail inputs with low-voltage operation down to 1.8 V, enabling ease-of-use in battery-powered applications.

Key features:

  • Reduces system size and cost: 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 significantly reducing the need for external discrete circuitry.
  • Greater DC accuracy: Two times lower offset drift and typical input bias across a full temperature range, -40 to 125 degrees Celsius, creates a more precise signal chain solution compared to other small devices.

Lower power, faster response with the tiny TLV7011 family of comparators

  • Smaller footprint, extra features: No phase reversal and integrated internal hysteresis for overdriven inputs increase design flexibility and reduce the need for external components.
  • Fifty percent less power consumption: With power as low as 335 nA and fast propagation delay down to 260 ns, the TLV7011 family of nano power comparators enable low-power systems to monitor signals and respond quickly.

These new devices join TI’s small-size amplifier portfolio which enables engineers to design smaller systems, while maintaining high performance, with industry-leading package options and many of the world’s smallest op-amps and comparators.

Designers can download the TINA-TI SPICE model to simulate their designs and predict circuit behavior 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 10.8-V/15-W, >90% Efficiency, 2.4-cm2, Power Stage Reference Design. Also, they can quickly and easily evaluate the TLV7011 comparators with the DIP adapter evaluation module, available today for US$5.00 from the TI store and authorized distributors.
