The DAC16 is a 16-bit high speed current-output digital-to- analog converter with a settling time of 500 ns. A unique com- bination of low distortion, high signal-to-noise ratio, and high speed make the DAC16 ideally suited to performing waveform synthesis and modulation in communications, instrumentation, and ATE systems. Input reference current is buffered, with full- scale output current of 5 mA. The 16-bit parallel digital input bus is TTL/CMOS compatible. Operating from +5 V and –15 V supplies, the DAC16 consumes 190 mW (typ) and is available in a 24-lead epoxy DIP, epoxy surface-mount small outline (SOL), and in die form.

AD515A is a monolithic FET-input operational amplifier with a guaranteed maximum input bias current of 75 fA (AD515AL). The AD515A is a monolithic successor to the industry standard AD515 electrometer, and will replace the AD515 in most applications. The AD515A also delivers laser-trimmed offset voltage, low drift, low noise and low power, a combination of features not previously available in ultralow bias current circuits. All devices are internally compensated, protected against latch-up and are short circuit protected. The AD515A is typically used for sensor and instrumentation measurement, ohmmeter, divider, voltage reference, DC voltage measurement and current sensor applications. The AD515A can be used to measure small currents or voltages from high impedance resistors or capacitors.
