3 Description
The OPA1652 (dual) and OPA1654 (quad) FET-input
operational amplifiers achieve a low 4.5-nV/√Hz noise
density with an ultra-low distortion of 0.00005% at 1
kHz. The OPA1652 and OPA1654 op amps offer railto-
rail output swing to within 800 mV with a 2-kΩ
load, which increases headroom and maximizes
dynamic range. These devices also have a high
output drive capability of ±30 mA.
These devices operate 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 per channel. The OPA1652 and
OPA1654 op amps are unity-gain stable and provide
excellent dynamic behavior over a wide range of load
conditions.
These devices also feature completely independent
circuitry for lowest crosstalk and freedom from
interactions between channels, even when overdriven
or overloaded.
The OPA1652 and OPA1654 temperature ranges are
specified from –40°C to +85°C.
