What are the key features of OPA2341DGSA/250?
- Rail-to-rail input and output swing on a single supply from 2.5 V to 5.5 V maximizes dynamic range in low-voltage portable and wearable designs
- Hardware shutdown pin reduces quiescent current to microamp-level standby, extending battery life in duty-cycled sensor nodes and IoT front-ends
- Ultralow 10 pA input bias current and 90 dB CMRR enable precise measurement of high-impedance sensors such as pH electrodes and photodiodes without loading the source
What is OPA2341DGSA/250 used for?
The OPA2341DGSA/250 targets single-supply battery-powered signal conditioning circuits where rail-to-rail swing and ultralow input bias current are critical, such as portable medical glucose monitors, wearable biosignal amplifiers, and pH or ion-selective electrode interfaces. Its 5.5 MHz gain-bandwidth product supports audio-range active filters and instrumentation amplifier stages with adequate phase margin at unity gain. The hardware shutdown feature allows the dual amplifier to be powered down between measurements, reducing average supply current in duty-cycled IoT sensor nodes.

Frequently Asked Questions
How low is the input bias current of the OPA2341DGSA/250, and which sensor types benefit from this specification?
The OPA2341DGSA/250 specifies a maximum input bias current of just 10 pA at 25°C, which is negligible compared to the source impedance of high-impedance sensors such as pH electrodes (up to 1 GΩ), ISFET biosensors, and reverse-biased photodiodes. At 10 pA, the voltage error across a 100 MΩ source resistance is only 1 mV, preserving measurement accuracy.
Can the OPA2341DGSA/250 operate from a single 3.3 V supply rail in a microcontroller-based system?
Yes, the OPA2341DGSA/250 operates from a single supply between 2.5 V and 5.5 V, making it fully compatible with 3.3 V MCU systems. Its rail-to-rail output swings to within a few millivolts of both supply rails, allowing the full ADC input range to be used without level-shifting circuitry.
What is the gain-bandwidth product of the OPA2341DGSA/250, and how does this limit closed-loop bandwidth in a gain-of-10 V/V stage?
The OPA2341DGSA/250 has a 5.5 MHz gain-bandwidth product. At a closed-loop gain of 10 V/V (20 dB), the usable bandwidth is limited to approximately 550 kHz. This is sufficient for audio frequency active filters, low-speed data acquisition up to 100 kSPS, and biomedical signal chains operating below 100 kHz.
How does the shutdown pin on the OPA2341DGSA/250 reduce power consumption in a duty-cycled measurement system?
When the shutdown pin is asserted, the OPA2341DGSA/250 enters a low-power state where quiescent current drops significantly below normal operating levels, typically to a few microamps compared to the active supply current. In a system that activates the amplifier for only 1 ms every 100 ms, the effective average supply current is reduced by up to 99%, directly extending battery runtime in coin-cell or small LiPo powered designs.
