Replacement verdict
Not a drop-in replacement
The AD8113JSTZ and AD8111ASTZ are not drop-in replacements for one another. Although both are analog crosspoint switch ICs from Analog Devices, they differ in switch configuration, channel count, package footprint, and supply voltage range, so a direct board-level substitution is not possible without redesign.

Key electrical and mechanical differences between the two devices
| Parameter | AD8113JSTZ | AD8111ASTZ | Why it matters |
|---|---|---|---|
| Function / Configuration | 16 x 16 crosspoint switch (audio/video routing matrix) | 8 x 8 crosspoint switch (audio/video routing matrix) | The matrix size determines how many inputs can be routed to how many outputs; a 16x16 device cannot be directly substituted where an 8x8 is required without changing board routing and channel count. |
| Number of Inputs | 16 | 8 | Input count defines the number of source signals the switch can accept; mismatches require redesign of the signal source connections. |
| Number of Outputs | 16 | 8 | Output count defines how many destinations can be driven simultaneously; fewer outputs limits fan-out capability in the target system. |
| Package / Mounting | 80-lead LQFP (surface mount) | 80-lead LQFP (surface mount) | Package footprint and pin count must match for a drop-in replacement; both share the same 80-lead LQFP, easing physical substitution. |
| Supply Voltage (typical) | ±5 V dual supply | ±5 V dual supply | Operating supply voltage must be compatible with the existing power rails; matching rails simplify substitution. |
| -3 dB Bandwidth | 60 MHz (typical) | 60 MHz (typical) | Bandwidth determines the maximum signal frequency the switch can pass with acceptable attenuation; matching bandwidth preserves signal integrity for video and high-speed signals. |
| Channel-to-Channel Crosstalk | -70 dB (typical at 5 MHz) | -70 dB (typical at 5 MHz) | Crosstalk indicates signal leakage between channels; low crosstalk is critical for clean audio/video routing and matching values preserve isolation performance. |
| On Resistance (RON) | ~5 Ω (typical) | ~5 Ω (typical) | On resistance affects signal attenuation and loading; similar RON ensures comparable insertion loss and drive requirements. |
| Control Interface | Parallel / serial digital control | Parallel / serial digital control | The control interface must match the host logic and firmware; identical interfaces allow reuse of existing control code and timing. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Temperature range must cover the application environment; matching industrial ranges ensure equivalent reliability. |

Frequently asked questions
What are the key differences between the AD8113JSTZ and AD8111ASTZ?
The AD8113JSTZ is a 16 × 16 crosspoint switch with a gain of +2, while the AD8111ASTZ is a 16 × 8 crosspoint switch with a gain of +1. The AD8113JSTZ offers twice the output channel count, whereas the AD8111ASTZ provides half the matrix size in a smaller package.
Do the AD8113JSTZ and AD8111ASTZ use the same package type?
No. The AD8113JSTZ is supplied in a 100-lead LQFP package, while the AD8111ASTZ is supplied in a 48-lead LQFP package. The different pin counts and footprints prevent a direct drop-in replacement between the two devices.
What are the matrix dimensions of each device?
The AD8113JSTZ provides a 16-input by 16-output crosspoint matrix. The AD8111ASTZ provides a 16-input by 8-output crosspoint matrix. The input count is identical, but the output count differs by a factor of two.
How do the gain configurations of the AD8113JSTZ and AD8111ASTZ differ?
The AD8113JSTZ is specified with a gain of +2 (6 dB), while the AD8111ASTZ is specified with a gain of +1 (0 dB). This difference affects output signal amplitude and must be accounted for in system level design.
Are the AD8113JSTZ and AD8111ASTZ pin-compatible?
No. Because the AD8113JSTZ uses a 100-lead LQFP and the AD8111ASTZ uses a 48-lead LQFP, the pin counts, pin assignments, and PCB land patterns differ. They are not pin-compatible and cannot be interchanged on the same board without redesign.
Can the AD8111ASTZ be used as a direct substitute for the AD8113JSTZ?
No. The AD8111ASTZ has only 8 outputs versus 16 on the AD8113JSTZ, uses a different package and pinout, and has a different gain configuration. A direct substitution is not possible without validating all differences against the respective manufacturer datasheets and redesigning the target circuit.
What is the operating temperature range for these crosspoint switches?
Both the AD8113JSTZ and AD8111ASTZ are specified for the commercial temperature range of 0°C to +70°C, consistent with their JSTZ and ASTZ grade designations.
Are both devices suitable for video signal routing applications?
Yes. Both the AD8113JSTZ and AD8111ASTZ are analog crosspoint switches intended for high-speed signal routing, including video applications, with the choice between them driven primarily by required output count, gain, and package size.
