Overview
The INA217AIDWT is a low noise, low distortion instrumentation amplifier manufactured by Texas Instruments. It serves as a replacement for the SSM2017 and is housed in a 16-pin TSSOP package. Key electrical specifications include a 3.4 MHz bandwidth, a slew rate of 15 V/us, and a common-mode rejection ratio of 100 dB. The device operates on supply voltages ranging from 9 V to 36 V with a quiescent current of 10 mA. Input characteristics feature a bias current of 12 uA and an offset voltage of 250 uV. It supports an operating temperature range from -40 C to +125 C.
Feature Summary
- Designed as a direct replacement for the Analog Devices SSM2017 instrumentation amplifier.
- Provides low noise and low distortion performance suitable for high-fidelity audio applications.
Applications
- Microphone preamplifier circuits
- Audio signal processing
Procurement Notes
Verify the specific suffix 'WT' against the official datasheet to confirm it denotes the tape-and-reel packaging variant within the INA217 family. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the pinout and thermal characteristics with the 16-TSSOP package dimensions before finalizing the PCB layout.
Selection Notes
Select this component when a low-noise instrumentation amplifier is required for audio applications needing a direct drop-in replacement for legacy SSM2017 designs. Consider the 16-pin TSSOP package constraints and the 9 V to 36 V single-supply operation range. Evaluate the 10 mA quiescent current against power budget requirements compared to lower-power operational amplifier alternatives.
Part Context
The INA217 series belongs to Texas Instruments' portfolio of precision analog amplifiers. Originally developed by Burr-Brown, these devices are engineered for high-performance audio systems. The INA217 specifically targets professional audio equipment where low distortion and high common-mode rejection are critical for maintaining signal integrity in microphone preamplification stages.
Replacement Considerations
Officially documented as a replacement for the Analog Devices SSM2017. Verify pin compatibility and gain settings when substituting into existing SSM2017 designs.
