INA1651-Q1 Datasheet | Texas Instruments

Features - 1 AEC-Q100 qualified for automotive applications - Temperature grade 1: - 40°C to +125°C, TA - High mon-mode rejection: 91 d B (typical) - High input impedance: 1 MΩ differential - Ultra-low noise: - 104.7 d Bu, unweighted - Ultra-low total harmonic distortion + noise: - 119 d B THD+N (20 d Bu, 22-k Hz bandwidth) - Short-circuit protection - Integrated EMI filters - Wide supply range: ±2.25 V to ±12 V - Available in small 14-Pin TSSOP package 2 Applications - Cabin microphone preamplifiers - Infotainment systems - Audio input circuitry - Line drivers - External audio power amplifiers 3 Description The INA1650-Q1 dual-channel and INA1651-Q1 single-channel (INA165x-Q1) Sound Plus™ audio line receivers achieve an extremely high mon-mode rejection ratio (CMRR) of 91 d B while maintaining an ultra-low THD+N of - 119 d B at 1 k Hz for 20-d Bu signal levels. Unlike other line receiver products, the INA165x-Q1 CMRR is characterized over temperature and tested in production to deliver consistent performance in a wide variety of applications. The INA165x-Q1 devices operate over a very-widesupply range of ±2.25 V to ±12 V. In addition to the line-receiver channels, a buffered midsupply reference output is included to allow the INA165x-Q1 to be configured for dual-supply or single-supply applications. The midsupply output can be used as a bias voltage for other analog circuitry in the signal chain. The INA1650-Q1 features a unique internal layout for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded.
