Texas Instruments (TI) introduced an operational amplifier (op amp) that features both zero-drift and zero-crossover technology.
The OPA388 op amp maintains precision across the entire input range for a variety of industrial applications, including test and measurement, medical and safety equipment, and high-resolution data-acquisition systems.
The design of the OPA388 produces a combination of ultra-high input linearity and precision.
TI’s zero-drift technology eliminates temperature drift and flicker noise to attain the highest DC precision and dynamic error correction, while its zero-crossover topology eliminates offset errors caused by common-mode limitations to achieve linear output and true rail-to-rail input operation.
Features include:
- Ultra-Low Offset Voltage: ±0.25 µV
- Zero-Drift: ±0.005 µV/°C
- Zero-Crossover: 140-dB CMRR True RRIO
- Low Noise: 7.0 nV√Hz at 1 kHz
- No 1/f Noise: 140 nVPP (0.1 Hz to 10 Hz)
- Fast Settling: 2 µs (1 V to 0.01%)
- Gain Bandwidth: 10 MHz
- Single Supply: 2.5 V to 5.5 V
- Dual Supply: ±1.25 V to ±2.75 V
- True Rail-to-Rail Input and Output
- EMI/RFI Filtered Inputs
- Industry-Standard Packages:
- Single in SOIC-8, SOT-23-5, and VSSOP-8
- Dual in SOIC-8 and VSSOP-8
- Quad in SOIC-14 and TSSOP-14
