extent, the sales manager is going to reconfirm the order and let you know if there
are any updates.
Shipping Cost
Shipping starts at $40, but some countries will exceed $40. For
example (South Africa, Brazil, India, Pakistan, Israel, etc.)
The
basic freight (for package ≤0.5kg or corresponding volume) depends on the time zone and
country.
Currently, our products are shipped through DHL, FedEx, SF, and UPS.
Delivery TimeOnce the goods are shipped, estimated delivery time depends on the shipping methods you chose:

OPA1678IDR Description
The dual-channel OPA1678IDR op amp outperforms traditional op amps frequently used in audio circuitry at the system level.
The OPA1678IDR amplifier has a low noise density of 4.5 nV/√Hz and low distortion of 0.0001% at 1 kHz, which improves audio signal fidelity. With a 2-kΩ load, these devices also provide rail-to-rail output swing to within 800 mV, increasing headroom and maximizing dynamic range.
The OPA1678IDR operates over a very wide supply range of ±2.25 V to ±18 V (or 4.5 V to 36 V) on only 2 mA of supply current to satisfy the power-supply limits of various types of audio equipment. Because the OPA1678IDR is unity-gain stable and has great dynamic behavior over a wide range of load circumstances, it can be employed in a variety of audio circuits.
Even when overdriven or overloaded, the OPA1678IDR amplifier uses totally independent internal circuitry for the lowest crosstalk and freedom from channel interactions.
OPA1678IDR Features
? Low noise at 1 kHz: 4.5 nV/√Hz
? Low distortion at 1 kHz: 0.0001 percent
? 114 dB of open-loop gain
? 110 dB of common-mode rejection
? Quiescent current is low:
– each channel 2 mA
? Input bias current is low: 10 pA (typical)
? Wide gain bandwidth: 16 MHz (G = 1)
? Slew rate: 9 V/μs
? Stable unity gain
? Output rail-to-rail
