This series also • THD+N: –136 dB (G = 1, ƒ = 1 kHz) offers rail-to-rail output swing, which maximizes dynamic range. • Offset Voltage: 180 μV (Max) • Offset Voltage Drift: 0.35 μV/°C (Typ) The extremely low voltage and low current noise, high speed, and wide output swing of the OPA2211- • Low Supply Current: 3.6 mA/Ch (Typ) EP series make these devices an excellent choice as • Unity-Gain Stable a loop filter amplifier in PLL applications. • Gain Bandwidth Product: In precision data acquisition applications, the 80 MHz (G = 100) OPA2211-EP series of operational amplifiers 45 MHz (G = 1) provides 700-ns settling time to 16-bit accuracy • Slew Rate: 27 V/ μs throughout 10-V output swings. This AC performance, • 16-Bit Settling: 700 ns combined with only 125 μV of offset and 0.35 μV/°C of drift over temperature, makes the OPA2211-EP • Wide Supply Range: ideal for driving high-precision 16-bit analog-to-digital ±2.25 V to ±18 V, +4.5 V to +36 V converters (ADCs) or buffering the output of high- • Rail-to-Rail Output resolution digital-to-analog converters (DACs). • Output Current: 30 mA The OPA2211-EP is specified over a wide dual-power • Supports Defense, Aerospace, and Medical supply range of ±2.25 V to ±18 V, or for single-supply Applications operation from 4.5 to 36 V. – Controlled Baseline The OPA2211-EP is available in a small DFN-8 (3- – One Assembly and Test Site mm × 3-mm) package.
