PRODUCTION DATA. OPA1641-Q1, OPA1642-Q1 SBOS791 – JUNE 2017 OPA164x-Q1 SoundPlus™ JFET-Input, Automotive-Grade, Audio Operational Amplifiers 1 1 Features 1 • Qualified for Automotive Applications • AEC-Q100 Qualified With the Following Results: – Device Temperature Grade 1: –40°C to +125°C Ambient Operating Temperature – Device HBM ESD Classification Level 2 – Device CDM ESD Classification Level C6 • Low Noise: 5.1 nV/ √Hz at 1 kHz • Ultra-low Distortion: 0.00005% at 1 kHz • High Slew Rate: 20 V/μs • Unity Gain Stable • No Phase Reversal • Low Quiescent Current: 1.8 mA per Channel • Rail-to-Rail Output • Wide Supply Range: ±2.25 V to ±18 V • Single, Dual, and Quad Versions Available 2 Applications • Automotive • HEV and EV Power Train • Advanced Driver Assist (ADAS) • Infotainment Systems • In-Cabin Microphones 3 Description The OPA1641-Q1 (single) and OPA1642-Q1 (dual) series are JFET-input, ultra-low distortion, low-noise operational amplifiers (op amps) fully specified for audio applications. The rail-to-rail output swing allows increased headroom, making these devices ideal for use in any audio circuit. Features include 5.1-nV/ √Hz noise, low total harmonic distortion + noise (THD+N) (0.00005%), a low input bias current of 2 pA, and low quiescent current of 1.8 mA per channel. These devices operate over a very wide supply voltage range of ±2.25 V to ±18 V. The OPA164x-Q1 series of operational amplifiers are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions. The dual version features completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded.
