ISL5861 is a 12-bit, 130/210+MSPS CMOS, high speed, low power D/A (digital to analog) converter, designed specifically for use in high performance communication systems such as base transceiver stations utilizing 2.5G or 3G cellular protocols.
The ISL5861 is a 12‑bit, +3.3 V, high‑speed D/A converter designed for communication systems such as base‑transceiver stations using 2.5G, 3G, or 4G protocols. It provides selectable speed grades of 130 MSPS or 210 MSPS, low power operation (≈1 W at 130 MSPS), and an adjustable full‑scale output current from 2 mA to 20 mA.
The device is supplied in SOIC and TSSOP packages, operates from –40 °C to 85 °C, and includes features such as 3 V LVCMOS‑compatible inputs, internal 1.2 V reference, and pin‑compatible replacement for AD9752 and HI5860. Detailed electrical, timing, and package specifications are provided in the datasheet.
| Resolution | 12 bits |
|---|---|
| Supply Voltage | +3.3 V (AVpp = DVpp = +3.3 V) |
| Full‑Scale Output Current | 2 mA to 20 mA |
| Low Power Consumption | ≈1.04 W at 130 MSPS, 20 mA output |
| Operating Temperature Range | -40 °C to 85 °C |
The ISL5861 can operate at up to 210 MHz (210 MSPS) for the /2IA and /2IB versions, and up to 130 MHz (130 MSPS) for the A and B versions.
The device uses a +3.3 V supply for both analog (AVpp) and digital (DVpp) rails.
The full‑scale output current can be set between 2 mA and 20 mA.
The ISL5861 is rated for operation from –40 °C to 85 °C.
