The OPA2991-Q1 is an automotive-grade dual 40V, 4.5MHz low-power operational amplifier
The OPA2991-Q1 family (OPA991-Q1, OPA2991-Q1 and OPA4991-Q1) is a family of high voltage (40V) general purpose operational amplifiers for automotive applications. These devices feature excellent DC accuracy and AC performance, including rail-to-rail input/output, low offset voltage (±125µV typ), low temperature drift (±0.3µV/°C typ), low noise (10.8nV/ √ Hz and 1.8μV PP) and 4.5MHz bandwidth.
With unique features such as differential and common-mode input voltage ranges for power rails, high output current (±75mA), high slew rate (21V/μs), and high capacitive load drive (1nF), the OPA2991-Q1 is a robust and reliable The AD9613BCPZ-250 high performance operational amplifier for high voltage automotive applications.
The OPA2991-Q1 family of operational amplifiers is available in standard packages such as SOT-23, SOIC, VSSOP, and TSSOP and is specified for operation over the –40°C to 125°C temperature range.
