The AD1154 is a high accuracy, low cost sample-and-hold amplifier (SHA) designed for use in high resolution data acquisition systems. It features a gain of +1 V/V and includes internal hold capacitor and proprietary compensation circuitry to ensure 16-bit accuracy with fast A/D converters.
The document provides detailed electrical specifications, including nonlinearity, droop rate, aperture jitter, and temperature ranges for both 'A' and 'B' grades. It also covers functional block diagrams, pin descriptions, grounding considerations, and application circuits.
| Nonlinearity (Sample Mode) | +0.0015 % |
|---|---|
| Aperture Jitter | 150 ps |
| Input Voltage Range | +10 V min |
| Small Signal Bandwidth | 1 MHz |
| Acquisition Time to +0.00076% | 3.5 ps (5 max) |
| Temperature Range | -25°C to +85°C |
| Package Type | 14-Pin DIP |
The AD1154 has a noninverting architecture with a gain of +1 V/V.
The 'A' grade is specified for 15-bit accurate systems, while the 'B' grade offers superior performance for true 16-bit applications.
It is recommended to bypass both power supplies with 0.1 µF ceramic capacitors in parallel with 10 µF tantalum capacitors located as close to the device as possible.
