3 / 21 page LM1973 www.ti.com SNAS093B – DECEMBER 1994 – REVISED MARCH 2013 ELECTRICAL CHARACTERISTICS (1) (2) The following specifications apply for all channels with VDD = +6V, VSS = −6V, VIN = 5.5 Vpk, and f = 1 kHz, unless otherwise specified. Limits apply for TA = 25°C. Digital inputs are TTL and CMOS compatible. LM1973 Units Parameter Test Conditions (Limits) Typical (3) Limit (4) IS Supply Current Inputs are AC Grounded 3 5 mA (max) THD+N Total Harmonic Distortion plus Noise VIN = 0.5 Vpk at 0dB Attenuation 0.0008 0.003 % (max) XTalk Crosstalk (Channel Separation) 0dB Attenuation for VIN 110 dB (5) VCH measured at −76dB SNR Signal-to-Noise Ratio Inputs are AC Grounded at −12dB Attenuation 120 110 dB (min) A-Weighted AM Mute Attenuation 104 96 dB (min) Attenuation Step Size Error 0dB to −16dB ±0.05 dB (max) −17dB to −48dB ±0.1 dB (max) −49dB to −76dB ±0.25 dB (max) Absolute Attenuation Error Attenuation at 0dB 0.01 0.5 dB (min) Attenuation at −20dB 19.8 19.0 dB (min) Attenuation at −40dB 39.5 38.5 dB (min) Attenuation at −60dB 59.3 58.0 dB (min) Attenuation at −76dB 74.5 73.0 dB (min) Channel-to-Channel Attenuation Attenuation at 0dB, −20dB, −40dB, ±0.5 dB (max) −60dB Tracking Error Attenuation at −76dB ±0.75 dB (max) ILEAK Analog Input Leakage Current Inputs are AC Grounded 10.0 100 nA (max) RIN AC Input Impedance Pins 2, 4, 18, VIN = 1.0 Vpk, f = 1 kHz 40 20 k Ω (min) 60 k Ω (max) IIN Input Current at Pins 9, 10, 11 at 0V < VIN < 5V 1.0 ±100 nA (max) fCLK Clock Frequency 3 2 MHz (max) VIH High-Level Input Voltage at Pins 9, 10, 11 2.0 V (min) VIL Low-Level Input Voltage at Pins 9, 10, 11 0.8 V (max) Data-Out Levels (Pin 12) VDD = 6V, VSS = 0V 0.1 V (max) 5.9 V (min) (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional. Electrical Characteristics state DC and AC electrical specifications under particular test conditions and specific performance limits. This assumes that the device is within the Operating Ratings. The typical value is a good indication of device performance. (2) All voltages are measured with respect to GND (pins 1, 3, 5, 14, 17), unless otherwise specified. (3) Typicals are measured at 25°C and represent the parametric norm. (4) Limits are specified to TI's AOQL (Average Output Quality Level). (5) At the present time the Crosstalk measurement is specified as a typical only, which is due to a hardware limitation of the automated test equipment.
