Tiny op-amps deliver high performance for IoT, smartphones

Texas Instruments (Dallas, TX) has introduced what it says are the industry's smallest operational amplifier (op amp) and low-power comparators for Internet of Things (IoT), personal electronics, and industrial applications.

Offered in a compact X2SON package measuring 0.64 mm 2, the TLV9061 op amp and TLV7011 family of comparators are designed to reduce system size and cost while maintaining high performance in a variety of IoT, personal electronics, and industrial applications. These include mobile phones, wearables, optical modules, motor drives, smart grid, and battery-powered systems.

The TLV9061 op amp is designed for use in wide-bandwidth, high-performance systems. Key features include a gain bandwidth (GBW) of 10 MHz, slew rate of 6.5 V/µs, and a low-noise spectral density of 10 nV/√Hz.

The op amp also features integrated EMI filtering inputs, which helps reduce susceptibility to RF noise while reducing the need for external discrete circuitry. In addition, compared to other small devices, says TI, the device's 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.

The TLV7011 nanopower comparators, compared with competitive products, deliver a faster response time with propagation delays down to 260 ns, while consuming 50 percent less power, says TI. In addition, no phase reversal and integrated internal hysteresis for overdriven inputs increase design flexibility and reduce the need for external components.

The TLV7011 nanopower comparators have a power consumption as low as 335 nA and a propagation delay down to 260 ns. Both the op amp and comparators support rail-to-rail inputs with low-voltage operation down to 1.8 V, enabling ease-of-use in battery-powered applications.

Preproduction samples of the TLV9061 op amp and volume quantities of the TLV7011 comparators are available in a five-pin extra-small-outline no-lead (X2SON) package, measuring 0.8 mm x 0.8 mm x 0.4 mm.
