Advanced Linear Devices, Inc. Quad/Dual N-Channel Depletion Mode MOSFET Array/Pair ALD114913SAL

The ALD114913SAL is a dual N-channel depletion mode MOSFET array in an 8-pin SOIC package, designed for low-voltage, low-power analog applications requiring precision matched pairs. It operates as a normally-on device with a gate threshold voltage of -1.30V ±0.04V and a typical on-resistance of 1.3 kΩ at VGS = 0V. The device exhibits matched threshold voltage within 20 mV, input impedance of 10^12 Ω, and extremely low gate and drain leakage currents. It supports single-supply operation from 1.5V to ±5V and features tight parametric control across batches. The package measures 4.69 mm to 5.00 mm in length, 3.50 mm to 4.05 mm in width, and 1.35 mm to 1.75 mm in height. It is rated for an operating temperature range of 0°C to +70°C and meets RoHS standards as indicated by the 'L' suffix. Applications include precision current sources, zero-power fail-safe circuits, and sub-threshold biased analog interfaces.
