The TLR1901GXZ, an ultra-compact CMOS operational amplifier (op amp) from ROHM, has the lowest operating circuit current in the industry. This integrated circuit is designed to function as a measurement sensing amplifier in applications with limited dimensions, including wearable technology, indoor motion detectors, and handheld measurement instruments.
Sensors that measure variables like temperature, humidity, vibration, pressure, and flow rate, as well as the operational amplifiers (op amps) that amplify these sensor outputs, are becoming increasingly important as the need for increasingly complex control in battery-powered devices grows. Simultaneously, achieving a sustainable society requires apps to be more compact and energy-efficient, which places comparable expectations on individual devices.
ROHM has improved its manufacturing, packaging, and proprietary Nano Energy circuit technologies in response to these changing market demands.
The result is an op amp that satisfies three essential needs: reduced power consumption, increased accuracy, and small size. By using a WLCSP (Wafer Level Chip Scale Package) with a fine ball pitch of 0.35mm, the recently developed TLR1901GXZ achieves an ultra-compact footprint of less than 1mm2 while offering an industry-leading low operating current of 160nA (typ.).
This results in a much longer battery life in addition to enabling high-density mounting in applications with limited space.
Moreover, the TLR1901GXZ Features:
- An exceptionally low input offset voltage of just 0.55mV (max.), one of the best among ultra-low current op amps.
- This represents an approximate 45% reduction compared to typical products on the market.
- A maximum input offset voltage temperature drift of 7uV/°C ensures high accuracy operation over the operating temperature range.
Design flexibility can be further enhanced by pairing the op amp with ROHM’s ultra-compact general-purpose resistors, such as the MCR004 (0402 metric / 01005 inch) and MCR006 (0603 metric / 0201 inch), for applications like gain adjustment.
The MCR004?series lineup includes the MCR004E –an environmentally friendly, fully lead-free option designed to support sustainable designs.  Adapter boards featuring SSOP5 package ICs are offered as well to support initial evaluation and replacement assessments.
Going forward, ROHM will continue to pursue further power savings in op amps by advancing both miniaturization and original ultra-low power technologies.
At the same time, we are committed to improving device performance by reducing noise and offset, expanding power supply voltage ranges, and contributing to solving social issues through more precise application control.
