Texas Instruments OPA4202
The OPA202, OPA2202, and OPA4202 (OPAx202) are a family of devices built on TI's industry-leading precision super-beta, complementary, bipolar semiconductor process. This process offers ultra-low flicker noise, low offset voltage, low offset voltage temperature drift, and excellent linearity with common-mode and power-supply variation. These devices offer an exceptional combination of dc precision, heavy capacitive load drive, and protection against external EMI, thermal, and short-circuit events.FEATURES
●1 Precision super-beta performance: – Low offset voltage: 200 µV (maximum) – Ultra-low drift: 1 µV/°C (maximum)● Excellent efficiency: – Quiescent current: 580 µA (typical) – Gain-bandwidth product: 1 MHz – Low input voltage noise: 9 nV/√Hz
● Ease of use, design simplicity: – Heavy capacitive load drive: 5-µs settling time with 25 nF – Ultra-high input impedance: 3000 GΩ and 0.5 pF – EMI hardened, thermal, and short-circuit protection
● Stable Performance: – High CMRR and AOL: 126 dB (minimum) – High PSRR: 126 dB (minimum)
● Low bias current: 2 nA (maximum)
● Low 0.1-Hz to 10-Hz noise: 0.2 µVPP
● Wide supply voltage: ±2.25 V to ±18 V
● Replaces OP-07 and OP-27 2
