Engineering Selection Recommendations
For Direct Replacement (100Ohm On-State Resistance):
The MAX399 series (MAX399ESE+, MAX399CSE+, MAX399ESE+T, MAX399CSE+T) provides electrical equivalence to the PS399ESE with identical on-state resistance, circuit configuration, and supply voltage ranges. All MAX399 variants are active products with ROHS3 compliance and MSL 1 rating. Selection between these parts depends on packaging requirements: tube packaging for MAX399ESE+ and MAX399CSE+, or tape & reel for MAX399ESE+T and MAX399CSE+T. Operating temperature ranges differ: MAX399ESE+ and MAX399ESE+T support -40°C to 85°C, while MAX399CSE+ and MAX399CSE+T support 0°C to 70°C.
For Higher Supply Voltage Applications (200Ohm On-State Resistance):
The ADG1209YRZ and ADG1209YRZ-REEL7 support extended supply voltage ranges (5V to 16.5V single supply, ±5V to ±16.5V dual supply) with improved switching performance (95ns/100ns versus 150ns/150ns). These parts maintain 2-circuit SP4T configuration and 4:1 multiplexing. The ADG1209 series exhibits lower charge injection (0.4pC) and superior channel-to-channel matching (4.6Ohm). Operating temperature extends to -40°C to 125°C. On-state resistance doubles to 200Ohm, requiring circuit analysis to confirm compatibility.
For Extended Temperature Range (210Ohm On-State Resistance):
The ADG1309BRZ-REEL7 provides 2-circuit SP4T functionality with -40°C to 105°C operating range and improved leakage characteristics (1nA maximum). On-state resistance is 210Ohm with 5Ohm channel matching. Supply voltage range is 5V to 16.5V single supply or ±5V to ±16.5V dual supply. This part is suitable for applications requiring extended temperature operation with moderate on-state resistance tolerance.
For Single-Circuit Applications (400Ohm On-State Resistance):
The MAX4709ESE+ is a single-circuit 4:1 multiplexer with 400Ohm on-state resistance and extended supply voltage capability (9V to 36V single supply, ±4.5V to ±20V dual supply). This part is not a direct substitute due to reduced circuit count and significantly higher on-state resistance. Selection requires confirmation that single-circuit operation and 400Ohm resistance are acceptable for the application.
Frequently Asked Questions (FAQ)
Q: Can MAX399ESE+ directly replace PS399ESE in all applications?
A: The MAX399ESE+ provides electrical equivalence in on-state resistance (100Ohm), circuit configuration (2-circuit SP4T 4:1), and supply voltage ranges (3V to 15V single, ±3V to ±8V dual). Both parts are ROHS3 compliant with MSL 1 rating. The primary difference is package size: PS399ESE uses 16-SOIC (0.295", 7.50mm width) while MAX399ESE+ uses 16-SOIC (0.154", 3.90mm width). PCB layout modifications are required to accommodate the smaller package footprint.
Q: What is the impact of increased on-state resistance in ADG1209 and ADG1309 substitutes?
A: On-state resistance directly affects signal attenuation and power dissipation. ADG1209 parts feature 200Ohm resistance (2x PS399ESE), while ADG1309 parts feature 210Ohm resistance. Applications with low-impedance signal sources or tight attenuation budgets require circuit analysis. Switching speed improves with ADG1209 (95ns/100ns versus 150ns/150ns), and charge injection decreases (0.4pC versus 2.8pC), potentially offsetting resistance increases in precision applications.
Q: Are packaging format differences between tube and tape & reel significant?
A: Tube packaging (MAX399ESE+, MAX399CSE+) and tape & reel packaging (MAX399ESE+T, MAX399CSE+T, ADG1209YRZ-REEL7, ADG1309BRZ-REEL7) are functionally identical. Selection depends on assembly process requirements and procurement volume. Tape & reel packaging is standard for automated pick-and-place assembly, while tube packaging is common for manual assembly or lower-volume applications.
Q: Why does MAX4709ESE+ have different circuit count?
A: MAX4709ESE+ is a single-circuit 4:1 multiplexer versus the 2-circuit SP4T configuration of PS399ESE. This fundamental architectural difference makes MAX4709ESE+ unsuitable as a direct replacement. Selection requires confirmation that single-channel multiplexing satisfies application requirements.
Q: What are the supply voltage compatibility constraints?
A: PS399ESE supports 3V to 15V single supply or ±3V to ±8V dual supply. MAX399 series maintains identical ranges. ADG1209 and ADG1309 series require minimum 5V single supply or ±5V dual supply, making them incompatible with 3V single-supply applications. MAX4709ESE+ requires 9V to 36V single supply or ±4.5V to ±20V dual supply. Verify supply voltage compatibility before substitution.
Q: How do operating temperature ranges affect part selection?
A: PS399ESE operating temperature is not specified. MAX399ESE+ and MAX399ESE+T support -40°C to 85°C. MAX399CSE+ and MAX399CSE+T support 0°C to 70°C. ADG1209 series supports -40°C to 125°C. ADG1309BRZ-REEL7 supports -40°C to 105°C. Applications requiring operation below 0°C or above 85°C require ADG1209 or ADG1309 selection.
