Product details
Overview
LTC6226IS6#TRMPBF from Analog Devices is a single-channel, rail-to-rail output, unity-gain stable operational amplifier optimized for high-speed, low-noise signal conditioning. It delivers 420MHz gain-bandwidth product, 180V/µs slew rate, and 1nV/√Hz input voltage noise, enabling precision driving of 16-bit ADCs like the AD7380 at 4Msps sampling rates with 91dB SNR and –104.8dB THD.
For engineers reviewing the LTC6226IS6#TRMPBF datasheet, LTC6226IS6#TRMPBF pinout, LTC6226IS6#TRMPBF application, or LTC6226IS6#TRMPBF equivalent, key selection criteria include its 6-lead TSOT-23 package, –40°C to 85°C operating range, shutdown functionality (350µA disable current), and verified performance at 3V/5V/10V supplies with rail-to-rail input common-mode range extending to V–.
Technical Context
The LTC6226IS6#TRMPBF employs a proprietary high-speed bipolar complementary architecture to achieve simultaneous low noise (1nV/√Hz), high slew rate (180V/µs), and unity-gain stability without external compensation. Its input stage includes negative rail–referenced common-mode operation and bias cancellation circuitry, supporting true single-supply use down to 2.8V total supply.
Internal shutdown control asserts high-impedance output and reduces supply current to 350µA while maintaining fast turn-on (2100ns) and turn-off (800ns) timing. The device maintains >114dB open-loop gain and >114dB CMRR across –40°C to 85°C, ensuring stable closed-loop behavior in precision active filters and transimpedance configurations.

FAQ
What is the maximum supply voltage for LTC6226IS6#TRMPBF?
The absolute maximum total supply voltage (V+ to V–) for LTC6226IS6#TRMPBF is 12V. It is fully specified across 2.8V to 11.75V, with guaranteed performance at 3V, 5V, and ±5V supplies. Exceeding 12V risks permanent damage per Absolute Maximum Ratings.
Does LTC6226IS6#TRMPBF support true single-supply operation?
Yes, LTC6226IS6#TRMPBF supports true single-supply operation: its input common-mode range extends to V– – 0.1V, and output swings rail-to-rail. With V– tied to ground and V+ at 3V or higher, it handles ground-referenced inputs and delivers full-scale output swing-ideal for 3V microcontroller-based signal chains.
What is the typical shutdown current of LTC6226IS6#TRMPBF?
The typical shutdown current of LTC6226IS6#TRMPBF is 350µA per channel at –40°C to 85°C. This is measured with SHDN pin held at V+ – 2.75V (disable threshold), and includes reduced quiescent current while maintaining fast 2100ns turn-on time-critical for power-gated portable instrumentation.
Can LTC6226IS6#TRMPBF drive 100Ω loads effectively?
Yes, LTC6226IS6#TRMPBF drives 100Ω loads with minimal degradation: output swing remains within 200mV of rails at 5mA sink/source, and harmonic distortion stays below –93dBc (HD2) at 1MHz with 4VP-P output. Its 100mA short-circuit current capability ensures robustness during transient overload.
Is LTC6226IS6#TRMPBF pin-compatible with other members of the LTC6226 family?
Yes, all LTC6226 variants in the 6-lead TSOT-23 package-including LTC6226HS6#TRMPBF (–40°C to 125°C)-share identical pinout and footprint. Only temperature grade and ordering suffix differ; electrical specifications (GBW, noise, slew rate) are identical across I-grade and H-grade S6 packages.
