ISL3283EFHZ - Miniature Broadband Gain Stage 70 - 3000 MHz
M/A-COM’s MAALSS0034 broadband gain stage is a GaAs MMIC amplifier in a lead-free SOT-89 surface mount plastic package. It can be operated from a single 3 to 5 volt supply.
operational amplifiers (op-amps)
| Feature | LM387 | MCP6002 |
|---|---|---|
| Type | Low-noise audio op-amp | General-purpose CMOS op-amp |
| Voltage Supply | ±3V to ±18V | 1.8V to 6V (single supply) |
| Bandwidth | ~4.5 MHz | ~1 MHz |
| Noise Performance | Low noise (optimized for audio) | Higher noise than LM387 |
| Power Consumption | Higher | Lower (low-power design) |
| Rail-to-Rail I/O | No | Yes |
| Input Impedance | High (audio optimized) | High |
| Best for | Audio applications | Battery-powered, general use |
| Alternative Chip | Key Differences/Advantages |
|---|---|
| MCP6022 | Higher bandwidth (10 MHz vs. 1 MHz), lower noise |
| TLV2372 | Similar specs, slightly better bandwidth (3 MHz) |
| TLV9002 | Lower power consumption, similar bandwidth (1 MHz) |
| OPA2333 | Higher precision, lower offset voltage |
| LM358-dat | Similar voltage range but not rail-to-rail |
| TSV912 | Lower voltage noise, better for precision applications |

Noninverting Amplifier
rail to rail
Rail-to-Rail Input & Output (RRIO)
Both the input and output can swing close to both power rails (VCC & VEE).
Example: MCP6002, TLV9002, OPA2333
Non-Rail-to-Rail Op-Amps
Neither input nor output reaches the full supply range.
Example: 741 op-amp (Needs at least ±12V to operate properly).
