What are the key features of AD8691AUJZ?
- Rail-to-rail output swing with 1.5 V to 5.5 V single-supply operation enabling full dynamic range in low-voltage 3.3 V and 5 V systems
- 1 mV maximum input offset voltage ensuring precise DC signal conditioning without trimming in sensor interface circuits
- 1.3 MHz gain-bandwidth product in a compact 5-pin TSOT-23 package ideal for space-constrained portable and wearable designs
What is AD8691AUJZ used for?
The AD8691AUJZ is suited for battery-powered portable instruments, IoT sensor nodes, and precision analog front-ends where low supply voltage and accurate DC performance are required. Its rail-to-rail output and 1 mV offset make it effective in transimpedance amplifier stages for photodiode current sensing and in active low-pass filters preceding low-power ADCs. The miniature TSOT-23 footprint and wide 1.5 V to 5.5 V supply range allow it to interface directly with microcontrollers and SoCs running from 1.8 V to 5 V supply rails.

Frequently Asked Questions
What is the maximum input offset voltage of the AD8691AUJZ, and how does it affect DC measurement accuracy?
The AD8691AUJZ specifies a maximum input offset voltage of 1 mV, which at a closed-loop gain of 100 V/V introduces no more than 100 mV of DC output error, making it sufficient for 8-bit to 10-bit ADC front-ends in temperature sensing, pressure sensing, and light intensity measurement applications.
Which supply voltage rails are compatible with the AD8691AUJZ in a single-supply configuration?
The AD8691AUJZ operates from a single supply between 1.5 V and 5.5 V, covering 1.8 V IoT microcontroller rails, 3.0 V single-cell alkaline batteries, 3.3 V digital logic supplies, and standard 5 V system rails, eliminating the need for a split or boosted supply in most portable designs.
How does the AD8691AUJZ's 1.3 MHz gain-bandwidth limit its usable closed-loop bandwidth?
With a 1.3 MHz gain-bandwidth product, the AD8691AUJZ provides approximately 130 kHz of small-signal bandwidth at a closed-loop gain of 10 V/V, or about 650 kHz at unity gain, which is adequate for audio-band signal conditioning, slow sensor averaging filters, and DAC output buffers in low-power systems.
For a compact wearable PCB, how does the TSOT-23 package size compare to an SO-8?
The 5-pin TSOT-23 package of the AD8691AUJZ measures approximately 1.6 mm × 2.9 mm, occupying less than 5 mm² versus roughly 20 mm² for a standard 8-pin SO-8, making it approximately 4× smaller and enabling tighter component placement in wrist-worn biosensors and hearing-aid analog circuits.
When should a designer choose the AD8691AUJZ over a dual op-amp in a single op-amp application?
A designer should choose the single AD8691AUJZ when only one amplifier stage is needed, as it avoids powering an unused second amplifier, reducing quiescent current consumption compared to a dual package, and the 5-pin TSOT-23 footprint fits into PCB areas as small as 3 mm × 4 mm where a dual 8-pin package would not.
