Its 16-bit resolution provides 65,536 discrete output levels from a 5 V analog supply — each LSB step is roughly 76 µV, which matters when the downstream ADC or comparator needs fine-grained setpoint control without post-filter gain. Integral nonlinearity is ±4 LSB maximum, and differential nonlinearity is ±0.5 LSB maximum — the DNL spec guarantees monotonicity, so every code increment produces a positive voltage step. This is essential for closed-loop systems where a non-monotonic DAC could cause the loop to hunt or latch. Settling time is 20 µs typical to ±0.5 LSB, which sets a practical update rate around 50 kHz. For waveform generation or servo setpoint updates, the system clock must budget this delay between write cycles. ## Parallel interface with 5 V rails — legacy bus ready Data is written via a parallel interface — all 16 bits are latched in one write cycle, no serial clock needed. This suits DSP or FPGA buses that already have a 16-bit data path and can drive the control signals without an SPI or I²C wrapper. Both analog and digital supply rails are 5 V (nominal), so no separate level translator is required when the host logic also runs at 5 V. The reference can be external or internal, giving flexibility to scale the output range. Packaged in a 28-lead SSOP (0.154-inch body width, 3.90 mm), surface-mount. The tube delivery suits medium-volume pick-and-place; the 0.0256-inch pin pitch is compatible with standard 0.65 mm pitch SSOP footprints. ## Temperature grade and compliance Rated for the commercial temperature range of 0°C to 70°C. This limits deployment to controlled indoor environments — industrial enclosures with ambient above 70°C or outdoor telecom shelters would need a wider-temperature variant.","metaTitle":"LTC1657CGN#PBF 16-Bit DAC, 28-SSOP, Voltage Output, Active","metaDescription":"LTC1657CGN#PBF 16-bit voltage-output DAC from Analog Devices.
