Low noise microphone pre-amp
25 September 2002, Analogue, Mixed Signal, LSI

Texas Instruments' INA217 low-noise, low-distortion microphone preamplifier from the company's Burr-Brown product line targets low-level audio signals in professional microphone and transducer amplifier applications. Features near-theoretical noise performance for 200 Ohm source impedance (1,3 nV/rtHz at 1 kHz). Unique distortion cancellation circuitry reduces distortion to extremely low levels, even in high gain (0,004%, G=100). Wide supply voltage, superior output voltage swing and high output current drive make it ideal for use in high-level audio stages. Current-feedback circuitry help achieve wide bandwidth (800 kHz, G=100) and high dynamic response over a wide range of gain. Key specifications: 1,3 nV/rtHz voltage noise, 800 kHz bandwidth (G=100), output swing 2 V from rails, ±10 mA quiescent I, >100 dB CMR, ±4,5 V to ±18 V supply range. The INA217 is available in DIP-8 and SOL-16.
