OPAx206 Input-Overvoltage-Protected, 4-µV, 0.08-µV/°C, Low-Power Super Beta, e-trim™ Operational Amplifiers 1 Features 3 Description
• Integrated input overvoltage protection up to ±40 V The OPA206, OPA2206, and OPA4206 (OPAx206) beyond supplies are the next generation of the industry-standard • e-trim™ operational amplifier performance OPAx277 family with the added feature of input – Low offset voltage: 25 µV (max) overvoltage protection. These precision, bipolar, – Low offset voltage drift: ±0.5 µV/°C (max) e‑trim™ op amps with super-beta inputs use TI’s • Super beta inputs proprietary trimming technology to achieve an input – Input bias current: 500 pA (max) offset voltage of ±4 μV (typical) and an input offset – Input current noise: 110 fA/√Hz voltage drift of ±0.08 μV/°C (typical). The input • Low noise overvoltage protection activates when the input signal – 0.1-Hz to 10-Hz: 0.2 µV exceeds the supply range and protects up to 40 V PP – Voltage noise: 8 nV/√Hz beyond either supply. This feature eliminates the need • A for external circuitry to prevent amplifier damage, OL, CMRR, and PSRR: > 124 dB (full temperature range) thereby reducing size and costs. • Gain bandwidth product: 3.6 MHz The OPAx206 provide a speed-to-power ratio of • Low quiescent current: 240 µA (max) 3.6 MHz for a mere 220 μA (typical). These devices • Slew rate: 4 V/µs also achieve a low voltage noise density of only • Overload power limiter 8 nV/√Hz at 1 kHz. The super-beta inputs of the • Rail-to-rail output OPAx206 have a very low input bias current of 100 pA • EMI and RFI filtered inputs (typical) and a current noise density of 110 fA/√Hz. • Wide supply: 4.5 V to 36 V • Temperature range: –40°C to +125°C The high performance of the OPAx206 make these devices an excellent choice for systems requiring
